I don't see how this would work other than by assigning different IP addresses to the same server or at least using different ports. What am I missing?

Perhaps I wasn't as clear about the use case as I thought I was:

I'd like to be able to use the same user (say "git") on multiple git repositories on the same host, distinguished only by the hostname, but reaching different logical accounts with different credentials. Just like http://host1/blog and http://host2/blog can point to different installs of Wordpress on the same server (both of which have a user "admin" through the web interface that have nothing to do with each other), I'd like git commits by the same user for different virtual hostnames on the same server to have different credentials, and reach different repositories.

Think mass hosting of git installs (or gitolite, or gitorious, or ...) on the same host just like virtual HTTP hosting at your typical Wordpress host.

I think this is an issue unrelated to my problem / suggestion.
