Also in reference to a broker approach. I think the concept should be that a bus instance could connect to an existing bus. This allows for the main bus to understand what buses are available without having to know about them originally. It also allows for scaling as you can throw up a bus pointed to the main bus in minutes and the main bus routes work to the other buses based on what they can handle.
