UPDATE: The relay network has been updated to use Bitcoin FIBRE - you can find th enew instructions to peer with it at
http://bitcoinfibre.org/public-network.html.
Many of you have likely seen the recent discussions on the P2Pool thread and the post on
the foundation blog about the relay network.
It exists as a way for pool operators (and all miners, though not hashers) to get their blocks relayed quickly across a separate network both as a backup to the P2P network and as a quicker way to get the latest blocks as it skips relaying transactions which have already been seen. Thus, if you're a miner anywhere from a small p2pool miner to a large pool, you should be running one of the relay network clients.
