In there a guide to serving VMs over network?

I like to setup a lab where users can have access to various versions of Windows (XP, Vista, 7). PRoblem is I have team of 20 engineers who at any tie 10 of them might need to have access to all these OSes.

What is the best solution?
I have a Windows 7 machine (can be other OS) that is running VBox and I have created all the guest OSes that I need.

I know I can enable remote display, but does that allow me to run just one remote connection at a time? (I guess so)
If so then do I need to run several instances of each guest OS?

Any other way to solve this ?

Any help is appreciated.

Get a dl360 with a dual xeon quad core, stuff it full of ram, attach a sas6gb storage card in it and a sas6gb storage unit in raid1, install one of the many free vbox management tools and of you go. Its that simple.

Thanks, for the tip about hardware.
My question was mostly about software.
How do I set vbox up to be able to serve several instances of an OS?
For example, Do I install Window XP as a guest os once and then several people can remote connect to it?

The not so clear part for me is how do I serve an OS to several users?

If more then one needs a VM then you need more VM's and their licenses, access is easy via RDP.
