You can listen to the "new-selected-pair" signal, it will tell you which
candidates have been selected.. But I agree it would be good to add such
an API for completeness.

Are you aware that the libnice reliable mode is not TCP, but a custom
TCP-over-UDP implementation (that is compatible with the one used by
Google Talk). And it's definitely not compatible with UDT, which is a
completely different protocol. So you need to be using libnice on both
sides (or libjingle) to send and receive. Alternatively, you could try
to put libnice below UDT, but I'm not sure how the UDT code works.

Also, if you end up using a TURN relay, you need to send through
libnice, as the packets are encapsulated.
