Shouldn't we scuba-oriented types be pooling our resources to look
beneath the sea instead of in outer space?  I've seen quite a few
movies where there's some alien or magical being or force inhabiting
the deep and those were just as believable as any invasion from space-
type movies.

I propose SAUI: the Search for Alien Underwater Intelligence.  Instead
of networking computers together, we could network dolphins and enlist
their aid in finding the mermaids from Mars.  I am currently accepting
donations to fund the purchase of the first rec.scuba SAUI dolphin,
which will begin intensive training in my pool as soon as it arrives.
Of course I will selflessly donate the upkeep and training expenses of
the dolphin from my own pocket, including video rental fees of all the
underwater alien movies I can find so the dolphin knows what to look
for.

Any other rec.scubans with pools or access to pools can then apply for
their own dolphins and we'll wire them together with cellular
technology, eventually setting our wired dolphins loose in the oceans
to seek out and destroy any alien invaders before they get us first.
This might even win me the Nobel Peace Prize.
