[Nice] what threads are needed?

Ok, well, I guess that's not my problem then!

I feel like I'm very close...

I have two agents... both of which are getting their local candidates,
serializing them and sendthing them to the other...

Both of them are also sending their local credentials to each other and
calling "nice_agent_set_remote_credentials()" on them...

They are both talking to my stun server, and I believe that all of the
information is being serialized and deserialized correctly (it's safe to use
nice_address_to_string() and nice_address_set_from_string() to serialize and
deserialize the NiceCandidate->addr and NiceCandidate->base_addr members

BTW, do I need to set the "NiceCandidate->username" and
"NiceCandidate->password" fields if I am seperately sending the credentials
( I currently am both sending them as part of my NiceCandidate serialization
process and seperately for calls to set_remote_credentials())...?

The behaviour that I'm seeing is that my componet state never changes to
4... it goes right from 2 to 5... then a send() of course fails...
