Umm... I'm not absolutely sure this is true. Would it not show some
statistical evidence of the multiplexing? I admit it might be subtle, and I
agree that Arecibo would be of limited utility. I think the idea of the Frank
Drake crowd is to assume that "they" *want* to talk to "us", and would go for
something like a tin can on a string near a watering hole. If "we" want to
look for "their" "Ophiuchi Hotline[s]", that is a different matter. IMHO,
YMMV, etc.


Personal to Danny: You're almost there. I suggest actually using a search
engine once in a while. :) :)
