[Battlemesh] Mesh Routing Protocol Comparison

Hey Mortiz,
This data is fantastic. Thank you for putting this together. I'm surprised that the cjdns DHT stuff 
didn't come in last at everything. That algorithm is deprecated but left on because it does work 
when no route server is available. I'd really like to migrate to Yggdrasil algorithm for these cases.

Obviously I'd love to have the kind of scaling properties of something like Babel, but cjdns and 
Yggdrasil have the additional constraint of having been designed to operate in an environment with 
hostile nodes.

When I read the mobility testing, I'm not completely clear as to whether I'm looking at drop rate of 
pings between nodes who have themselves changed peer relationships, or between stable nodes in a 
globally dynamic network. In the second case I would intuitively expect to see a good showing from 
Yggdrasil since it will just switch to tree routing when it gets confused. However if the 
destination moves then that has to go through the DHT, and we might find this is in fact hobbling 
the protocol.

If this is in fact the case, then my intuition is that the DHT nodes should gossip link state 
updates to their keyspace neighbors and communicating nodes should be able to subscribe to receive 
link state updates of those with whom they have active sessions.
