I'm running at home off a DSL circuit. I host using a mixture of virtual FreeBSD servers under Parallels on an Intel Mac Mini and two real servers. It works pretty well for low traffic web sites, but the VM's need to have a real hardware NTP server to keep their clocks syncronized. I also run NFS on real hardware. It works surprisingly well. Watch how you allocate VM disk I/O across your physical disk spindles. I have three physical drives plugged into the mini.
