Well, if you can implement a LTSP-like solution, good for you. In my
case all users already had local linux workstations running C5, the XP
was needed only for a couple of proprietary applications and for a
limited period of time. The problem came from the fact that despite
using what I call pretty decent hw, most of the users did not have
hardware capable of doing full virt but we had to start the project
really FAST ( The software supplier informed me that the proprietary
applications cannot run on linux the very day the project started,
despite doing 3 months of preparations for the project). Basically I had
no choice but create VMs on a server with spare resources (which
happened to be in another city than the users). Your use case is

It's not really like you describe it. With the proper patch, several
different RDP users can share the VM, just as an 2003 server would do
for more money. In our case, this was important because - at least in
the beginning of the project - the number of simultaneous users exceeded
the number of available VMs
As of VNC sharing the console .. I am not sure what are you speaking
about. As far as I know, VNC is quite reluctant to share a single
desktop with several users, unless the connections are R/O. And in a LAN
the speed is acceptable, but via remote links VNC quickly becomes
"unpleasant". If you go the VNC way, I strongly suggest to examine NX

I have only networked printers, too, but in this case it was not about a
printer but a hardware toy (ASIC development board).
