True, though whether those programs will work with PulseAudio is
questionable.

Today, I upgraded my Ubuntu home desktop to Feisty and installed the ltsp
stuff.  I have a slightly later version of some packages than you tested
which may explain differences.

I tried a few things:

1.  PXE booted my laptop

2.  Added myself to the pulse groups (not sure if this was necessary)

3.  Started Rhythmbox and played some music very clearly.

4.  Tried to adjust volume which didn't seem to work.  I then opened up
    the gnome mixer and realised that I just needed to select the pulse
    mixer device.  After that volume changes worked fine.

5.  Played a 1GB mp4 video full screen on the thin client with some frame
    loss, though it was very watchable.

6.  Logged out, logged in as a different user and did all of the above
    again.

I'm _very_ impressed.

On the server do:

	sudo chroot /opt/ltsp/i386 
	passwd
	exit

which will set the password for root on the clients.  You can then hit
<ctrl><alt><F1> for a shel l and login.
