Ok, that was the motiviation I did not get from your original
message.  It begins to make sense somewhat.

Another approach to do the same I can think of, without having
to add 50 new accounts for 50 users, would be to collect a ssh
key from each of these 50 users, and have 1 line per user in the
authorized_keys file of gitadmin.gitadmin user (who owns the
repository with the paranoia hook that decides the authorization
aspect of the repository).  The authentication would come from
the environment="Name=value" option in the authorized_keys file.
Each of your aunt tillies can push or fetch over ssh using the
key she has in the gitadmin.gitadmin's authorized_keys file.

I suspect the "hackiness" factor from the aesthetics viewpoint
is probably about the same, but this would work with the current
code without patches, no?
