Nexenta is an operating system built on top of the OpenSolaris core and the Debian userland.
Beagle is the Mono-based desktop search that we implemented at Novell (similar in spirit to Google Desktop search or Apple's spotlight).
F-Spot is our personal photo management software.
This is great, and we look forward to help the Nexenta developers with any issues they might have with Mono on OpenSolaris.
Although to reach magnificent-hack status we still need Sun and Apple to ship Mono.
Oh, and if you have not seen the video from the previous blog entry, you should.
