One problem I'm noticing is that the session-policy XML allows specifying the bandwidth in each direction, but SDP does not (as far as I can tell).  How should we resolve this?  Should we define directional bandwidth modifiers in SDP?  Or should we restrict bandwidth in a stream based on the directionality attributes of the stream?

That is, if the sending bandwidth is limited to 10,000 and the receiving bandwidth is limited to 100,000, then an a=sendrecv stream would be have b=10000 but an a=recv stream would have b=100000.
