Really?:) Duh! But seriously, even though I've quoted people who've
developed such models -- on this list no less! -- I'm not sure about any
such models' ability to do so. Still, I guess it can't hurt, but it might
attract attention, especially if you have to get time on some of the
supercomputers... or does what seti@home is doing, which might even get more

One would think.

I would stay away from the Congo project for two reasons. One, it would
cost a lot. Two, the region is extremely politically unstable right now and
probably will remain so for the next few years.

Correlation or cause? I guess we can test it out.:)
