Thanks for the fast answer. I admit I was expecting such a reply... :)

However, since we're covering the subject, there's a feature that I 
think could be safely and harmlessly added anyway, i.e. getting 
information upon the negotiated codecs in a channel. Currently the only 
way to understand which audio and/or video codec has been negotiated is 
waiting for a frame and look at its subclass: which means that, as long 
as no frame is received, there's no way to know this. The same 
information polling approach could also apply at several other aspects 
of the underlying media, since, while signaling protocols are a lot, 
always RTP is used.

Lorenzo
