Gorry-

Thanks for the comments.

Fair enough.  I am adding a reference.

The latter.  I guess I am not quite sure what to do with this comment.

I think so.  Are you suggesting here that we specify a different value
when we're going over IPv6?  I am not sure if that is a 2581bis thing or
a 1122bis thing.

In the intro to section 3 I have put these words:

    Also note that the algorithms specified in this document work in
    terms of using loss as the signal of congestion.  Explicit
    Congestion Notification (ECN) could also be used as discussed in
    [RFC3168].

Does this work?
