I don't really understand what you are trying to say. I'm concerned that 
if I use jails there will be multiple redundant copies of common 
programs like Gnome, all stored in virtual memory. So the virtual memory 
requirement would go out the roof and we'd miss most of the benefit of 
thin clients.
