Well no. Are we going to use a hierarchical, peer-to-peer or hub based system? Before we decide on the message format, protocol for exchanging the messages and a transport standards for exchanging them over, then we really have to decide on what sort of topology we're talking about. There are fundamental differences between building a standard around an entirely peer-to-peer architecture, than building one which uses a central hub!
