Ah, just remembered one thing. If memory serves, FreeNX dates back to 
the same time that multiseat project was started. They were developed 
targeting a very similar use case, but different in the end, while 
multiseat had a faster time-to-market, I think.

Places like some public libraries, like we have here in Brazil, uses 
multiseat. Keeping these running is much easier than having someone with 
the knowledge to fix a virtualization host when it goes rogue. These 
places here have 0 tech people working in there..

Note that multiseat doesn't even require a network at all. You can 
always open up a text editor and do some writing, or some spreadsheet 
calcs...

It's been a while since I last used FreeNX. I didn't recall it being 
able to map drivers back then but good to know that x2go can do it, 
thanks. Back then it already was indeed much faster than VNC and/or 
remote X.
