Have the PM push over SSH, and don't ever expire reflogs on the
central repository?  The reflog will have the old and new commits
and the user name of the PM.

Downsides are:

- data is in the reflog on the central repository, to access it
  you need to expose that file via some non-git means (e.g. http
  or direct shell).

- one reflog record may cover multiple commits, so looking up a
  single commit is very difficult.  no current tools exist to merge
  the reflog back against the commit history to attach the record
  to a range of commits.

- the reflog is a text file, it will get somewhat large with time.

- the reflog is destroyed when the branch is deleted.  you may need a
  hook to forbid deletion of critical branches, so the reflog stays.
