That would be a major point for me, although video playback isn't at
first place. But e.g. mere browser usage is far too slow on our thin
clients, mainly because of slow graphics. This problem has become more
and more severe over the last year(s).

Can I have several different OS kernels for different breeds of clients?

Yes, my laptop is an older IBM T model with just that configuration, and
it still runs fine on current Linux. But I thought to buy more advanced
clients, maybe zbox or something like that. (Do you happen to know if
there are any glitches in graphics drivers for Linux on such machines?)

You convinced me :)
During the next weeks, our institute will move, so there's not much time
left for experiments. I will take all the old network with us and hope
to get it running at the new place. But after that, I will set up a
testing environment for a new configuration. Guess I will be back with
more questions then ;)
I would really like to stay with LTSP because a server/client
environment has many advantages over single PCs. But graphics has become
a major issue for us.

Rolf
