Yup. I know of a local data center that sells "virtual servers" using
VMware. They setup pre-made servers, such as an Apache or IIS web server,
and when they get a new client they just untar the package and run it under
VMware on a machine supporting several other clients with root access to
their own virtual machines. 

So it takes them probably around 30 seconds to bring a new server online
that they then charge monthly for. That's a good server management
technique.
