"virtual hosts"

Hi, found this through HN. Is there any plan to support "virtual" hosts the way HTTP servers do? This is a shortcoming of SSH that I've run into time after time, because SSH doesn't allow me to indicate what host I'm trying to connect to.

It seems like with the cert setup, the work is already half done, the biggest part of the work I'd imagine is just a way to specify multiple host names with multiple certs.

I'd be interested in contributing if this is something you'd like to see.
