[Nice] Making sense of it all...

[Tony Di Croce]

I've been working on the following test program... My goal for now was just
to see the callbacks fire as I gathered local candidates...

Unfortunately, I must be doing something wrong because my stund server never
gets hit and the only candidate type I detect is HOST...

I'm pretty sure there is something wrong with my code (as opposed to my stun
server) because I can run a stun command line client against my server and
the server gets hit (i know because it prints a bunch of stuff)... Any
ideas?
