Actually Warner, that usually works the -other- direction. I.e. you want
to be able to reduce the output when you are using a good directional
antenna.  Part of this is to comply with the 100mWatt EIRP regulation of
ISM. But more so to not over saturate a receiver at the other end or make
aggregation points possible. We regularly at www.wirelessleiden.net are
forced to swap a Senao card for a WMP11 just so that we reduce the power
on a link.  So right now; given that almost all cards output (a lot) less
than 100mWatt and that one or two connectors will easily half that - and
given that most people us directional antenna's - the legal argument would
argue for certanly the ability to -lower- the output of cards. Not worry
about people setting it higher.
