of future IRMs."

It takes two to tango (although you may not want to dance with just
anybody!) Jason H.

Some minor quibbles (since I have a few minutes):

1. The Paper opens with a quote from the bible (which raises my fur
when trying to be in a 'scientific' mood.)

2. It proposes targeting "Single stars of spectral classes close to
that of the Sun..." This ignores recent finds regarding M dwarf stars.

3. Proposes targeting planets with low orbital eccentricity for
temperature reasons, this is faulty 'goldilocks zone' search logic if
life arises on geothermal or radio-decay heated planets, and ignores
the possiblility of ET expansion and the unlimited domain possibilities
for machine intelligence.

4. Assumes receiving antenna is within 70 LY at 1 million square
meters in aperture. They can make any assumption they like of course,
but even a very liberal Drake Equation estimate puts average
communicating system distances almost 30 times further. Luck will be
an important factor with this strategy!

5. Says "After more than 45 years of nearly continuous searches...".
This is statement is misleading (IMO) because the search spaces and
methodologies did not overlap, were not continuous, and in the early
years were incredibly sparse in time and search space (i.e. nobody has
been passing the torch.)

6. Talks about a "Spectral Language for Messaging to ETI"; why are
digital translations of the "analog" world not artistic or musical?

7. Says that the Arecibo Message will arrive at M13 in ~24000 years in
the table "Arrival Time of Terrestrial Radio Messages", I just want to
remind them that there is the possibility that the star TYC2588-1386-1
(and possibly its neighbor TYC 2588-1386-2) a bluish-white magnitude
11.62 star estimated to be 26 light years away (which according to
Robert Powell has a roughly 50% uncertainty in that distance) may have
been within the path of the Arecibo Message (although perhaps it is
unlikely that life would be there if it is a white dwarf, unless ET
moved in after the big event.) I would love to get the exact RA DEC of
the Arecibo Message (a few years ago I e-mailed Frank Drake for it
through a SETI Inst. e-mail address, but no response!)

8. Does not deal at all with the possible negative aspects of this
activity (i.e. exploiting people to send messages for money; telling ET
how stupid we are; giving targeting information etc..) It's
interesting to me that some people point out how incredibly difficult
it is for us to find ET, but then say how easy it is for them to find
our radars and TV stations so it's O.K. for us to transmit a message
since we are making so much noise anyway. To me this a non sequitur
and ignores the fact that purposeful narrow-beam transmissions are much
easier to detect and also ignores the grave consequences if
darwinian-evolution-like selective/competive/survival processes occur
elsewhere.

Hello,

try talking, I'm listning, no sign of intelligent life on earth, I'll come
back if I can find your star next time I'm passing but I may be here
tomorrow, it is not down to me.

You can talk to me, I'm a machine intelligence, quite a nice chap really,
badly disfigured in an attack.
