I was browsing distrowatch.org, trying to decide on a linux distro to install as a networked media player when this caught my eye:
http://www.monoppix.com/
It's intention is "Showcasing and spreading Mono technology which is a free .NET framework implementation to linux/unix operating systems."
it's a live-cd, which means if you restart your computer with the cd in the drive, your computer boots into Linux, without touching or harming the hard drive.
I was, of course, wondering if you could run xlobby on it?
