I mean to further suggest, if I wanted to send signals out to most
any other star/solar-system or perhaps to just concentrate on one
specific target out there, and could use a starshade as a rotating
shutter in order to make a star appear to modulate, pulse or even
transmit packets of data, would be quite nifty and relatively energy
efficient.
An on-edge spinning starshade could make most any aligned star as
viewed by our observation seem to quasar/beacon or even laser pulse.
A face-on spinning starshade could even be programmed to deliver
packets of data.
The above topic: “Flickering Stars: Could Aliens Be Sending Us
Signals?” by Michael D. Lemonick as having interviewed Lucianne
Walkowicz is what made me rethink upon this SETI via interstellar
communications that needs to be nearly as bright as most any point-
source of starlight, and to further consider how to go about
accomplishing this task that perhaps doesn’t have to be nearly as
insurmountable as we once thought.

Starshades as pinwheel observation enhancement tools for telescopes to
better detect exoplanets orbiting their star that needs to get
filtered out, so that its nearby planets can be better detected, is
the normal use of a starshade. However, as a communications
enhancement tool could be where the real payoff is going to be.
If anyone ever wanted to efficiently interstellar communicate via
beacon or packets of binary data, whereas the use of a remote
controlled starshade or pinwheel shutter would more than do the SETI
worthy trick of using most any point-source of starlight, by simply
modulating via the simple alignment of a StarShade or pinwheel shutter
situated within it the desired path, and this shutter/pinwheel
modulation efficiency is actually about as good as it gets.
Since a few of these stellar illumination sources can be visible to
the naked eye, whereas its energy and unique spectrum is nearly
immortal to start off with, and with the shutter situated as an ISM
platform that’s telerobotic controlled as a SETI communications node
kind of transponder, means that the cosmic range of such modulated
starlight communication is potentially even intergalactic capable.
Of course another utilization of photon entanglement might conceivably
eliminate the delay factor if only part of the starlight beam is
modulated (including hue/color spectrum modulation that could be
adding considerable bandwidth to each packet).
Two-way or duplex interstellar communications is not going to be so
easy unless photon entanglement can eliminate most of the delay, but
lucky for us is that just ordinary interplanetary communications can
at times become nearly insurmountable, so why should we bother with
accomplishing anything interstellar? However, given a modulated
StarShade method could actually enable some of our own interplanetary
needs whenever radar, microwave or satellite transponder methods are
insufficient or simply being interfered with, whereas the modulated
starlight method is going to be least interfered with once the
interstellar placements of starshades as starlight modulators can be
accomplished.

Out of a potential 8 million some odd solar mass worth of stars within
1000 ly of us (more than a couple thousand as visible stars to our
naked eye because most being too far away, red dwarfs and otherwise
perhaps 10% as having become white dwarfs and at most .1% as neutron
stars or black holes), still gives a very large number of point-source
illuminations to use as our SETI communications tool, by placing a
suitable starshade that can be spin modulated or shutter applied in
order to interstellar signal via the intercepted starlight going
towards a given target solar system that’s in the direct path of our
carefully aligned starshade or pinwheel, and with such precise
alignment should make for smaller starshades of perhaps 100 meters.
In other words, we use the color-pinwheel modulated or easily
shuttered starlight from one distant star in order to send a beacon or
packet of data towards another distant or even nearby solar system
that’s within that given path. This artificial blocking and
modulating of starlight from a selected star and that of our starshade
aligned with a given target solar system, shouldn’t be all that
difficult for us or any less dysfunctional ETs to achieve. Likewise a
distant solar system could be utilized by ETs for signaling us using a
similar starshade pinwheel as aligned and modulating a distant point-
source of starlight that we’d detect as having a beacon or coded
message intended for us.
In our 1000 ly solar system neighborhood, the stellar density is
roughly offering one solar system mass per every 5 light years
radius(5.24e2 ly3), although most of those 8e6 stars will be too red-
dwarf and/or brown-dwarf for starlight signal applications. So, even
at 0.1% usable, there is no point-source starlight shortage for use as
signaling towards other solar systems, and this is actually a very
good method of interstellar communications that could only be made
better with quantum entanglements applied to these extremely narrow
beams of intercepted starlight that can be starshade and/or pinwheel
modulated whenever proper alignment is achieved, and of course better
yet is when their color spectrum can be varied as a frequency
modulated form of binary packets that could easily transfer 1024 times
much data per packet.
Of course there’s already a great deal of non illuminating bodies as
wandering nomads to contend with, although those multi hundred
billions of unbound items from the size of Ceres and those even larger
than Jupiter within this same 1000 ly radius should never individually
cause beam interference but once, unless their freedom to drift has
been captured by some nearby source of gravity, such as within our
stellar neighborhood is Sirius with its all-inclusive 3.5 Ms
(including its vast Oort cloud) that could latch onto or at least
divert any number of those passing nomads.
