Before you go out and buy all new clients. If I read correctly your
current ones are 500Mhz Celerons with 256MB. They *might* be good
enough to run Mplayer locally if that's what you mean by multimedia
apps. LTSP 5 is supposed to be easier to do local apps and I think
K12LTSP 7 is going to use LTSP 5. Even if you have video cards like
the Matrox G400 or the Radeon 9200 as Terrell suggests you can't
really have a whole lab all watching fullscreen video/sound
(headphones) at the same time. It will not only hammer your server
trying to decompress 30 video streams simultaneously but also saturate
even a gigabit linked eth0, not to mention video/audio sync problems
over the network. But you can do this with Mplayer as a local app.
Provided you have clients powerful enough.
