Adam,

I want to check on something:

If I bundle an m-line without a=ssrc, and with unique PTs, do you 
consider it ok if there are multiple "anonymous" flows each complying to 
the attributes of the m-line? Or do you assume that all packets with 
that PT are treated as one flow, switching from one SSRC to another as 
they are received?

	Thanks,
	Paul
