This was one of the major design wins when making LTSP 5 with Diskless.

Thank you for explaining this :)

This solves the browser plugin hell and the problem with network 
saturation. Given skilful design of the network with 2Gbit/s network 
card on the server side connected to 24 port 100 Mbit/s switch, I guess 
you could run 48 thin clients with moderate video and flash quality -- 
given that each switch got an 2Gbit/s input. 

Can you confirm or refuse this claim José, since it's really useful info 
when recommending network configuration for different client alternatives 
in schools :)
