The most efficient way to do it would probably be a bus, which might be
what you're suggesting. For a long time now there has been a plan to
migrate to an i2c bus. We ended up using serial as an interim
get-up-and-running-quickly approach. Not only will i2c be faster that
the async serial in terms of bits per second, there is no propagation
delays that depend on the number of nodes in the network.
