 ### Meeting
 When a new link is added to the network, between "first party" and "second party", the first party receives a "meet" event.
 The first party sends a meet message to the second party and enters talking mode.

+Note that a probe may be queued for sending, but by the time the sending node goes into talking mode, that probe might already be received
 from the other neighbour, so it's important to do the check at the actual time of sending and not at the time of queueing.

 ### Forwarding a probe
 When a probe comes in from one neighbour, if the probe wasn't seen before, a node should always forward it to all its other neighbours.

 too long, then many probe messages can be compressed into a relatively manageable file size for a batch of many probes, and the delay
 a node may build in before forwarding a batch of probes, will linearly decrease the bandwidth requirements.
 
 ### Detecting a loop
 There are a number of ways a probe can spread before a loop is detected. The simplest one is a probe that loops back to the node
