Hi Al,

I would support this work, not interested in directly contributing, and would periodically provide comments.

Thanks,

Barry

I think so, there are certainly implications to the return path
sampling process if the reordering occurs in the forward direction,
and the Src and Dst sequence numbers will not line-up, even if there
is no loss concurrent with the reordering...

Thanks for your review.  I'll try to update this again before the
meeting.  If I've overlooked some implications, let me know...

Would you support this as a chartered WG item?

Al
