Fine and cool for 1-1 bidirectional and symmetric streams. No longer
true for current more advanced needs.

I just hope that BUNDLE is a required step in order to separate each
RTP "sender" and RTP "receiver" within a RTP session, so in the future
we can get rid of SDP and design a proper RTP parameters based API for
WebRTC.
