A minor tangent, but it's got a pointer to a neat toy.
The Drake Equation (1961) is the classic articulation of the
potential for technological--and communicative--civilizations.
There's a neat toy at www.seti.org, too, that lets you plug in
values.
The basic "Drake Equation" info and site are at:
http://www.seti.org/seti/seti_science/drake_equation.html
One might also check out the book "First Contact," which
is a nice collection of essays; it was published around 1990,
and I forget off hand who edited it. It includes some very
interesting musings about the possible reaction of paranoid
civilizations to new noises in the neighborhood (including
the idea that a probe might be placed in the system by sub-
luminal methods; when it picks up noise, the robotic bomber
is duly dispatched.)
And, of course, it need not be pointed out too sharply that
intelligence has yet to show itself as anything other than
an evolutionary dead-end. Our track record is not incredibly
impressive (but I'd like to be optimistic).
