I know it may be a bit off base, but I'll ask anyway since someone has likely already tried.
We sometimes run into the "clients" (re kids/spouse using them) all being used when "someone" wants to play.
That said, assuming it is not backing up at the moment or serving up files, has anyone tried running Flight Simulator X on WHS?
I know the hardware is up to the task (note that server is also using XP drivers as well since no Server 2003 drivers were available) of running FSX.
Thanks.
