📝 Original message:See-also: Bitcoinrelaynetwork.org. It's already in use my the majority of large miners, is publicly available to anyone, and the protocol is rather simple and the client could be tweaked easily to keep exactly it's block ready to quickly relay to the nearest server (ie only have to relay the header, the coinbase transaction, and only small other data... Experience shows this is really easy to fit into one packet on the wire). It's not nearly as complicated as your suggestion, but may still marginally favor well-connected miners, but hopefully not much (when you're taking about single packets, it should all be latency, and the servers are well distributed). If you feel so inclined, there are some todos to make it really meet is efficiency limits filled on github.com/TheBlueMatt/RelayNode, feel free to rewrite the protocol if you really want :).
