Not much different. It uses the command feature of the authorized_keys
file of ssh to limit access to the 'gitosis-serve' command which is
given the username from the gitosis.conf as argument. gitosis-server
then takes care of the access control.

Yes definitely. It identifies the user not the host. Although you can
use differenty keys if you want.
