There are many other things that can cause erroneous bandwidth estimates, including various forms of tunneling (GRE, IPsec, 6to4) and link-layer encapsulation -- should those be discussed here?

I found section 3.5 on the potential interaction with DCCP somewhat lacking. It's clear that using DCCP for real time media will be different in a number of ways from the current flows over UDP, and while it is good that the draft notes the likely difference in header size, it hardly seems like the most important thing to note. The use of different congestion control algorithms seems far more salient; see draft-phelan-dccp-media-00.txt for a description of how TFRC's "contentment penalty" might apply when wrong guesses about available bandwidth come into play. That section of the draft may well date back some time, of course, so it may be unfair to ask for changes, and I certainly wouldn't block the draft for this. But a review by the DCCP folk might imrpove this a good bit; it also might show the need for a separate draft to discuss the DCCP-specific interactions here.
