Hi David,
I was wondering just about the same, i have a small cyber cafe and i would like to try with diskless workstations just for internet access, you know, no ftp no disk access at all, just borwsing, chatting, etc using X GUI and netscape or any other linux browser.
Right now i'm reading about this in different web sites, i'm a linux newbie but i'm very curious too so i read that you can install ltsp on redhat linux and e-smith as i know is based on redhat so it would be possible i think.
Thanks!
Jos
