I'm thinking layer 2 with a unique Ethernet packet type (probably use some abandoned packet type). That said, there's nothing stopping us from doing UDP, except the additional bandwidth. I don't see any need to do TCP. I think we can take advantage of Gigabit Ethernet's flow control mechanism (pause frames).
