I also would like to raise another point. The Seti Institute said that
the reason they do not post data is because for each star they scan they
accumulate 15 terabytes of data. I don't know how many of you are
computer professionals, or even know that much about computers, but that
is an extremely ludicrous number. They said all processing is done in
realtime. If you can show me a computer that can process 15 terabytes of
information into complex search algorithms in the short time they spend to
scan each star then I don't know what I'd do. It's impossible at this
point in time, even with an extremely large cluster to process 15
terabytes of data. Moby Dick is approx 200kilobytes in length last time i
checked. that makes each star's data 75,000,000 times the size of moby
dick, which I realize is not ascii text, but is still a number that is way
way off.

btw, I've used beowulf clusters on 1terabyte raid systems, and it has
taken WEEKS to do certain things. I'm sure the seti algorithms are
equally complex.
