In that general vein, an interesting project Robert Collins introduced me to last year is his lmirror work: https://pypi.python.org/pypi/lmirror It's designed to take advantage of various HTTP/2 features and the knowledge that it's specifically being used to create read-only mirrors to make the network operations more efficient than is feasible with the more general purpose rsync.
