Here is a way to work around this. Tell your friend to buy a four port router, something like a Linksys or Netgear. Now connect the router's WLAN connection to the network, and connect the Mac to one of the port. Enable MAC cloning on the router and set its value to the MAC address you need. Now your OS/X and all the VMs can have its own MAC address but they will all have the same MAC as seen from the network. Your friend will probably need to hide that router under his desk because network admin usually don't like people doing that. And I will not be responsible if your friend got himself into trouble for violating his company's policy but it is a work around.
