I'm with Gert on this.  Our hosting networks are all configured this  
way.  And, regarding the OP's comment about VPS, why view a virtual  
server any differently?   Each customer with either physical or  
virtual servers gets a vlan and IP allocation for those servers.   The  
virtuals quite happily vmotion around the network to their hearts  
content.  Each ESX cluster node gets to see the vlans for all the VM's  
on that cluster.  No big deal - it's just a dot1q trunk after all.
