The Seti team is still alive although we have dwindled down to a few
contributing members, it's been in existence for almost 8 or so
years.  I assume that the lack of paticipation is because nobody or
few people know about it.  It's a great way to dial in the overclock
on your PC, because when the client starts reporting compute errors on
the work units, you know you aren't stable.  I used this method to
tweak my system to total reliability.

Here's when you can get more info on the project and download the
client.
