I don't see why not - the technical details actually matter. Since the
servers will all share a socket, on any normal architecture, they'll all
have access to everyone's private keys. So, what is gained by having
separate certs?

I do agree that the process by which the additional names get added to
the main cert needs to reflect ownership of the name, but that's a
different matter.

And I'm not claiming, btw, that this mechanism is better than the server
name extension. However, I don't believe its as broken as some are claiming.

Cheers,

Ben.
