* when main cpu is idle (in loop), turn cpu clock rate down and/or activate special sleep modes. We want almost everything shutdown until it gets an interrupt.
# dynamic nodenum assignment tasks
we currently do the following crap solution:
hardwire nodenums based on macaddr. when node boots it broadcasts its Owner info (which includes our macaddr). If any node receives Owner messages, the other nodes reply with their owner info.
Really should instead do something like: new node sends its owner info as a provisional request. If any other node shows that nodenum in use by a different macaddr, they reply with NodeDeny.
If the node doesn't get denied within X seconds it then sends the info as a non provisional message (and other nodes update their node db)
But fixme, think about this and look for standard solutions - it will have problems when meshes separate change and then rejoin.
