No, because now start the problem: if I launch openoffice writer on pc n°1 it open a session on pc n°1 but if also pc n°2 launch openoffice writer there will be another session on pc n° 1. If also all the seven clients launch openoffice writer all the session are opened on pc n°1.

#1  with webmin 260 children is very easy to administrate as you can add 
them all at one time with a simple text file


#2  the animation is intense compared to open office or mozilla...and if 
you plan on running tuxmath on more than 1 or 2 clients you really MUST 
use a switch that takes GIG-E from the server to the clients...
CPU and RAM intensive also...so if you are running a mediocre(not that 
great) of a server then you are likely to see problems...and if your 
server only has a 10/100 network card you can pretty much forget about it.
