just add the hostname in the path when using --base-path and --user-path. this should be enough for most needs.
Signed-off-by: Pierre Habouzit <madcoder@debian.org> --- Here is a proposal for daemon side virtualhosting support.
This is quite simple, and just uses the hostname in the path where it looks for the git repository. Only works in conjuction of --base-path or --user-path btw.
