The licensing works in a way that you can only have it running on a single machine. I suppose you could do two registrations and have two servers running ESXi, but you couldn't manage both simultaneously. I have a server with an Athlon x2 3.0ghz CPU, 6gb of RAM, 7 network cards, and a single hard drive (the bottleneck). It can easily run anywhere from 6 - 20 virtual machines...but it depends on what VMs you are running.
