Google didnt 'choose' this restriction, its due to a fundamental
limitation of the SSL protocol. The current incarnation is not able to
support multiple domains per ip address. So the only workaround would
be to issue unique IP address*s* per domain - cant just use one in
distributed fault tolerent system, and there quite simply getting that
amount of IPs would be prohibitively complex and probably expensive.
