Video Mirror Drivers on 64-bit Platforms?

Hello.
I was reading through the list of unsupported features on XP and 2003
64-bit platforms, and was rather suprised to see both NetMeeting and
Remote Assistance listed as unsupported. Since both of these products use
mirror drivers (as does a product I’m working on), this peaked my interest
and got me to wondering if these products were just not ported and tested
in time for release.
Does anyone know if something changed with regards to mirror driver
support on 64-bit platforms?

Thanks…
