If you have read the email thread on this discussion, </span></font></tt><br>

find that steering committee need to decide whether openIB </span></font></tt><br>

on including the support for iWARP. Not that I am </span></font></tt><br>

<p><b><i><font size=2 color=navy face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:navy;font-weight:bold;font-style:italic'>[Ryan, Jim] The
Board of OpenIB is considering a proposal to formally support iWARP in addition
to InfiniBand. I believe formally expanding our charter would signal developers
and industry participants that OpenIB is undertaking this work as a complement
to what we’re doing with InfiniBand.</span></font></i></b></p>
<p><b><i><font size=2 color=navy face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:navy;font-weight:bold;font-style:italic'>A couple of
additional points. First, no one is saying OpenIB should “subsume control
of anything iWARP” – that’s quite a stretch from OpenIB
entertaining code submissions for iWARP as part of our Linux development activities.
Second, the statement the “steering committee” doesn’t
control the content of the source tree is correct in this arena. The steering
committee maintains the web site and other administrative activities,
including, potentially, sending the message to the industry of our interest and
support of iWARP. It does not control the activity of the open community –
I don’t think we could if we wanted to, and we don’t.</span></font></i></b></p>
<p><b><i><font size=2 color=navy face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:navy;font-weight:bold;font-style:italic'>To be as clear
as possible, if the steering committee were to vote against this proposed
expanded charter, the open community participants may well proceed with these
activities on their own.</span></font></i></b></p>

that helps, Jim</span></font></i></b></p>
