[K12OSN] Skype and audio in

The thing to remember with LTSP is that, by default, the applications run on the 
server, not on the clients; they just display on the clients.  That's why people 
were suggesting that 1GB of RAM was perhaps not enough memory for even just your 
three clients.  As for Skype, since the app is running on the server, just to 
test it, try plugging the mic into the server and it will probably work, 
although that's not likely what you want.

With that all said, LTSP 5 (K12LTSP uses LTSP 4.2, K12Linux uses LTSP 5) took a 
more standardized approach to sound on the clients, although not all apps work 
well with it.  LTSP 5 also has support for running apps on the client rather 
than the server (local apps).  A few other people have wanted to do what you 
what you're trying, and, if memory serves, they opted for running apps like 
Skype on the clients.  Search the LTSP mailing list archives for skype for details.
