[GRLUG] LTSP

I'd be surprised if there wasn't a live cd solution for a thin client 
setup though having the cdrom drive in is one more mechanical device 
that can fail, but shoot I have enough cdrom drives kickin around as 
they get replaced with cd/dvd burners. Scratched cd's are another 
concern, but I can burn more once I have master cd.

The live cd's are great as they are, but to be able boot them up already 
connected to network shares with home dir's already mounted would be 
great. I'd love to give my daughter her "customized" cd that she can put 
in any computer for her environment. I think the ideal setup would only 
require her password for access (and maybe user name).

Anyone see something like this?
