I think it would be very useful to get the softwires participatns'
position with respect to this draft. Specifically, if the draft
does solve their problem, then the softwires WG should document it
as a solution, and if not, then again the softwires WG should
document it with an explanation on why it does not solve their
problem.

Yakov.
