The big reason for wanting to virtualize is you have to keep 
incompatible versions of things running at the same time.  On a small 
home network that's probably not the case and you might be able to run 
all your services on the same system - or run the things you use less 
often under vmware with the centos-based k12ltsp as the host.

The beta releases of server had timeouts on the serial numbers but the 
current versions are supposed to be good forever.  Eventually xen may be 
better, especially on the newest 64-bit processors with hardware 
virtualization support but vmware is a safe bet now.
