Microsoft Virtual PC and Virtual Server

Information on Microsoft's "Virtual Machine" technology seems to be appearing now,
we've got some builds internally and they look really good.

The ability to base a new VM on another and only store the changes is really good,
saves loads of disk space! You can also drag/drop and use the clipboard between
VMs which is handy
