I had this very discussion with M$ at the launch of their new voip/comms version of Windows server, and the answer was you need *lots* of windows licences.

Principally
One for the server
One for each VPS
but there are some "interesting" additional licences needed if you're on multi-core/multi-cpu servers, to do with how many cores available to the VPS

The Hyper-V support is for virtualisation technologies, and is already a confusing area for licencing - to run a few windows VM’s on a Dual-Quadcore server currently needs about £450/month of Win2K3 licences - one per cpu, one per VM per core - so to run 3 VM’s each able to access all 8 cores requires a total of 26 licences @ £15/month each !!!
