OK.

I do not necessarily think so.  The entry points to transport on the
server side are quite limited (and the client side is dealing with
your own repositories anyway), and they already know which directory
in the server filesystem to hand to the upload-pack and friends, so
it would be a matter of passing GIT_DIR=$there when they call into the
run_command() API, if they are not already doing so.
