The problem is that there are some good drivers for 802.11b that
are open source (with some support from certain vendors), but the
802.11g stuff is a very closed architecture. Most of what little in
the way of open source drivers has been developed has been done the
hard way -- by people blinding poking around and seeing what happens.
And the situation just gets worse with USB devices, as opposed to PC
cards.
Active scanning isn't too hard, since you can piggy-back directly
on whatever existing OS-provided drivers are in place. But passive
scanning is a bitch, since you have to completely replace any
OS-provided driver with your own. And advanced features like
supporting re-injections is much, much harder.
