It would have been hard for me to miss it since I was the one that
made it. ;-)

Actually, I'm a greedy little b-stard. I want N-times increased
coverage and well over N-times as much spectrum. The whole cellular
pricing structure hinges on folks not having any alternatives. There
is *lots* of spectrum and the public is shoehorned into a few small

There is nothing magical about the cell-tower firmware that free/open
access point code couldn't also do. You want power control, WIFI
could do that if needed. You want hand-off to other frequencies, open
sourced code could do that too.

There is nothing preventing fair-share routing/filtering. This is
actually a common filter that both Linux and BSD kernels have
available in their IP filtering subsystems. In fact, there is a lot
of research on various different "fairness" algorithms. This is one
of the things that open-source will almost certainly do better since
there are tons of competing ideas and tons of research papers.
