In my Eskimo/New Yorker scenario of course, each has a
heartbeat etc and they both see the Sun/Moon sequences so they may use
these as a common reference to help them, so that's a bit of a cheat :-)

We may have a universe, with *many* ETI's then , whose sole knowledge
of each other is that they are there, and nothing more. What a frustrating

I never thought this would be possible anyway, my scenario not
even attempting to deal with moral values etc, which will only come if we
are ever in the position to 'shake hands with ETI' Without some feedback
from an alien(two way communication), all is *very* restricted.

So, even if the Eskimo/New Yorker *could be replaced* by two
powerfullPCs to speed things up, it would be a wasted effort. It's so
annoying to find that finally, there is a problem which our PCs
cannot tackle(?).....some might say it's refreshing. :-)

We can shake hands on that!
I shall use the Xmas recess to look at the web site of Marvin Minski
which Larry mentioned. It seems that there is nothing new under
this winter Sun, and I am in danger of boringly going over things
already well covered by yourself and many others.

I am much the wiser for it :-)
