It's about how many ports are used for a particular media stream, 
normally it's two, but it can be different. If there's a disagreement 
about this between the two sides, then I believe some of the pointers 
could be left NULLed. I haven't actually tested this though.

There's also the issue of a race condition due to incorrect locking. 
I've just pushed another commit to make this more robust. Either case 
requires reception of a stray UDP packet on a local port which is either 
unused or not yet used.
