Sorry E.T., but SETI@home, as we knew it, is no more. On December 15, 2005, the classic SETI@home project will stop issuing new work. However the project isn't entirely done with, as they are merging with BOINC for other distributed computing projects(yes, aliens are still on the menu). You can get more information(and the BOINC software) at the SETI@home homepage.
HotHardware is certainly no stranger to distributed computing projects, we've been active in the Folding@Home scene for years. If your interested in joining Team HH, you can get all the info you need in our forums.
