just thought that I would bring to your attention a product that I use alot called vmware. it lets your NT/2k/linux box host any number of other intel operating systems. the guest operating systems get their own memory space and cpu time but their disk is really a file on the host. best thing is that you can copy and paste the disks to clone guest operatins systems so you can trash them at will. also has an amazing feature where by you suspend and restore the guest operating systems to file lighting fast. I have a farm of virtual windows machines at work that I use of qa of code. the all sit on one server with a big disk.

version 3 is out at www.vmware.com.
