I never thought about this.. I've had the following problem in the past. Host A, cannot reach official github.com. But Host B can and has a local copy of a repo cloned. So Host B can 'git clone ssh://' from Host A which is essentially equivalent, but just setting origin to Host B instead of github.com, sort of acting as a manual proxy? What if Host A is natted, so Host B can ssh to Host A but not the reverse, can Host G ssh clone to Host A to push changes? In the rare times I've needed this, I just 'rsync -av --delete' a repo from B->A.
