The unsolicited LDP notifications from egress to ingress with 'adjusted' b/w info is meant to notify the ingress about the 'congestion' experience at egress based on traffic received from ingress over the PW. May be it can be clarified a little better. It is meant for 'any' traffic and not specific to client IP traffic. However, I believe eric rosen already has a draft in the area you are considering (http://tools.ietf.org/html/draft-rosen-pwe3-congestion-04) for PW congestion.

OTOH, I think at least Yaakov Stein and I are going to try take another run at producing a draft on congestion considerations (e.g., what happens when a fixed bandwidth IP pseudowire is mixed with congestion responsive IP traffic so that the two compete for limited forwarding capacity, and what should be done about it?), but we both have problems with our day jobs distracting us from IETF work, so this won't exactly be quick ;-). If this comes together, we should have at least a -00 draft for Paris, so I'd ask that the congestion considerations WG LC milestone be moved out to sometime next summer (or even September 2011).

Was wondering if PW-QOS-signaling (http://tools.ietf.org/html/draft-shah-pwe3-pw-qos-signaling-02) that proposed throttling from successor to predecessor PE (via feedback loop) is applicable to this charter?? Also, why proposed delete? No interest? p2mp difficulties?
