LTSP testing in Jaunty - how fat is local apps?

I can confirm this (ram more important) .

Testing with my clients some weeks ago : CPU  1GHz and 512 MB are enough 
to work fine as a (nubae) fat client.  (With 256 ram it was not possible 
in a good way)

But in my classroom now I use a Intrepid-ltsp with local apps and the 
help from "GetMoreFromLocalApps"
see https://help.ubuntu.com/community/UbuntuLTSP/GetMoreFromLocalApps

localapps are : firefox vlc wine and the games "lbreakout2 pingus fillets"
It is very easy and fast to install a new localapp and you have access 
to /home instead of /home/logged_in_user (<- last one I noticed testing 
jaunty-ltsp, only access to home/logged_in_user)
So I can use a folder named /home/wine for wine-windows-software where 
the localapp "wine" and all clients could access to.

With openoffice - I think- it is no problem to let it run on the server.
