The point has been made before that today customers are already going 5 to 10 Km
with 1000BASE-LX. There should be no debate that it is a market requirement to
go 5 to 10 km with 10 GbE.
While I am willing to consider accepting a conservative 2 to 3 km goal as the
official goal of the project, we need to acknowledge that this is a
conservative goal and, as we get on with the work of the project , we should
investigate whether we can stretch this goal..

I will gladly accept your suggestion of removing the portion of the
motion in parenthesis as a friendly amendment post-haste given your
support of this motion as a seconder.
