We, authors on IW10, take changing TCP seriously so we proceed with
scientific methods. We did these in live servers and lab tests to
achieve the best possible reality. We took feedbacks from IETF members
to refine our methods after two meetings. In the mean time, Ilpo from
U of Helsinki, and Michael Scharf from Lucent-Alcatel have each done
_independent_ experiments for IW10. None of us find any alarming
fairness issues between IW10/IW3.

For people who are concerned about possible problems of IW10 in
various network scenarios, can they kindly volunteer to help verify
these issues by similar testbed/live experiments? If IW10 turns out to
be a bad idea, we (tcpm/tmrg members) can all learn from these
studies/insights and figure a better solution.
