I think this must be syncronized with the work of the PILC wg. See

Patrik, thanks for drawing attention to this. Other activities
in the same arena that TSV has going on are ROHC and a proto-working
group (we'll be airing a draft charter for it soon) about end2end
considerations in mobility. It had a BOF (craps) in Pittsburgh, but the
scope of any WG will be more focuses than the BOF was.
