haha... it's a nice idea... perhaps a customized gentoo? it would probably be the easiest to make/maintain, since gentoo was designed to be source-based, making things easy to modify. When Promise releases their drivers, I'll be in on this project!
Isn't Gentoo almost just a live CD itself? I've never done anything with it, but I was going to install it before I noticed the lack of an installer like Anaconda. Now that FC2 is out, I'm going to give it a try (once I get the DVD burner to work..having some issues in that department). I'm going to talk around a bit and see what goes into making a distro. If anyone here is on a distro team, knowledge of it would be great :-)
