FreeBSD has 18 different Google Summer of Code projects, one of which is integrating our very own BSD Installer, among other very interesting ideas. There’s a wiki with information on a few of the proposals. NetBSD is also particpating, though there’s no list of accepted proposals online, yet. (hubertf will probably have something soon.)
Update: There’s a SourceForge project for the NetBSD Summer of Code work. (thanks, anonymous poster!) Ooh! Someone’s working on zeroconf!
