Yes. All of my current users have WinXP. I am merely moving their
workstations into VM's in order to increase their processing power.

Yes. Read-only secondary connections for support. Since this is a long
term solution (permanent), I get to design for sufficient resources.

I have one device in several of my offices that the vendor specifies a
brain-dead serial cable. I'm expecting this to be my only hardware hurdle.
