Well, perhaps I've asked the wrong person. <stares into monitor, imagining a grin>
The question seems legitimate to me, because if we assume a one in a million chance or less (as you've done), then the chance of locating ETIs doesn't merit the effort (unless, of course, you manage to earn a living collecting donations from SETI fans). In its present state of confrontational fragmentation (sorry about that) the human race can't even locate an enlightened master on their own planet.
