Good to hear that the project is alive and kicking!

Name Suggestions:
"Mobile Ruby" (though that sounds like a phone app)
"RIMP" (Ruby in my Pocket) (too bad is sounds like "GIMP")
"*Ruby" (instead of *nix)


"Ruby Live" as suggested by another poster also sounds pretty good,
though, in my opinion, "Live" sounds a bit generic since it's a common
distro title.  As you can see though, I'm not comming up with anything
better.  ;)

As for a logo, the normal tux colored ruby red sitting on
traintracks/rails would look pretty damn sweet.
