So you could make the temporary object repository persistant between pulls
to avoid reloading them across the wire.  Something like:

get_commit(sha1)
{
	if (sha1 in real_repo) -> done
	if (!(sha1 in tmp_repo))
		load sha1 to tmp_repo
	get_tree(sha1->tree)
	for each parent
		get_commit(sha1->parent)
	move sha1 from tmp_repo to real_repo
}

get_tree(sha1)
{
	if (sha1 in real_repo) -> done
	if (!(sha1 in tmp_repo))
		load sha1 to tmp repo
	for_each (sha1->entry) {
	  case blob: if (!sha1 in real_repo) load to real_repo
	  case tree: get_tree()
	}
	move sha1 from tmp_repo to real_repo
}

The "load sha1 to xxx_repo" needs to be smarter than my dumb wget
based script ... it must confirm the sha1 of the object being loaded
before installing (even into the tmp_repo).
