It is already in Debian; i haven't heard anything from the Fedora or
(Open)SuSE communities.

The implementation in Breezy is fairly simplistic, but should meet many
people's needs.  We're working out modern designs for some more advanced
features like local device support and sound during the UBZ summit in
Montreal right now, where we have sizeable chunks of both the Ubuntu and
LTSP development teams in the same room.

Somewhere out on the todo list, I'd like to make "fatter clients" trivial to
set up, but as you've seen, the existing implementation makes it quite
straightforward to set up if you know what you want and are willing to dig
into it.
