Thanks to Wayne Shulz for this update.  His MAS90 Knowledge is among the best, (except for me :)  Just kidding Wayne)

The above are all supported for Sage MAS90 and MAS200 version 4.3 and for MAS 500 v7.2.  In MAS500 version 7.3, MIcrosoft Windows 2008 Terminal Services, Virtual PC 2007 and Hyper-V for Windows 2008 will be support soon.
