iStat
iStat is an app that shows performance statistics of different machines. I compiled their iStat Server on my x86_64 machine and made a little DEB package. Download: istatd_0.5.4_x86_64.deb I also uploaded it to my PPA at launchpad.net. (If you own a Linksys NSLU2, you might want iStat Server (ARM).)
