I threat the query from Anoop pragmatically, currently he is only interested
in Window scaling. Window scaling underlies no MUST/SHOULD/COULD/WHATEVER
semantic. Sensor networks for example can disable window scaling where on the
other hand satelite/internet2 networks requires the full range of scaling.

Window scaling is a option where the user can and should use the value that
fits into his particular environment. This generates a lot of varities - but
with good cause. ;-)


Cheers, Hagen
