When you have a client object (e.g. by calling
dulwich.client.get_transport_and_path), you should be able to call
client.fetch("/path/to/remote/repo", r) where r is an instance of
dulwich.repo.BaseRepo. This will call fetch_pack under the hood for you.

We need a wrapper for send_pack that can do The Right Thing, but for now
you should be able to call it like this:

client.send_pack("/path/to/remote/repo",
r.object_store.determine_wants_all,
r.object_store.generate_pack_contents)

(also untested).
