How about NFSNET? http://www.nfsnet.org/
It's not doing anything *really* immediately useful, but it does have some
pure mathematical uses, and nobody ever knows what sort of things pure-math
ends up creating :P The only problems with it is that it uses a ton of RAM,
a ton of hard drive space, and the client is pretty bad. The first two
aren't really much of a problem, since it would be easy to (1) limit it to
high-speed computers, and (2) let people disable it if they want. The third
would be solved by using the distributed.net client :P
The request files are tiny - however, the result files are much larger,
which might cause some problems.
