OK, where can I buy it? I want some for my computer room. Along with
some decent insulation and double-studding the walls, that'd be an
awesome way to both keep the outside heat *and* noise out :)

That's a novel idea. Use your swimming pool water as chiller water for
your cooling system. The downside is that your swimming pool gets warm
and doesn't provide the same relief from the heat as it did before, but
it's definitely a good idea. I'd bite. Pumping the water through the
system has *got* to be cheaper than running the closed-system
evaporative compressor. Most of us with swimming pools (sadly, I'm not
one of them) have the pump and filter running almost all the time
anyways, so this wouldn't add much to the electric bill (if at all). It
would also be nice if it could somehow take advantage of the latent
cooling the ground might provide, but something tells me this wouldn't
last too terribly long with 90+ degree water flowing through it.
It'd definitely be worth a shot. Something to consider when I end up
buying a house. :)

Don't overlook that the increased water temperature will increase
evaporation. A small amount of evaporation has a tremendous cooling
effect. But it will also increase the rate at which you need to
rebalance the pH of your pool.
I don't know if such a thing exists, but another way to keep a house
cool would be a thin metal screen (think like a security screen door)
covering the roof with a few inches gap in between. The attic would not
get nearly as hot from the sun beating down on it. I've never seen such
a thing, so it's probably impractical, but have often thought about
implementing it (tho probably /not/ a good idea if you live near tornado
alley or in hurricane areas).
A rock wall for your southern exposure would also help, especially if
inside a glass wall. It will help in the wintertime to absorb heat
during the daytime and release it into the home at night. And in the
summertime, the sun won't hit it during the day, so during the daytime
it will help by absorbing the ambient heat within the house, and release
it at night.
There are quite a few alternative cooling systems available nowadays.
