namewould benefit from a multi-domain certificate because in this case, the wildcard certificate
would not work. In fact, if the organization was using wildcard certificates, two wildcard certificates
would be required because the root domain name is different in each case.

VirtualSpaceShip.com, www.VirtualSpaceShip.ws, www.VirtualCDVD.com,
