I'm sure the telcos would love to take over 802.11, but I don't see how 
that could happen, as most 802.11 installations are in private homes 
and businesses. The best they can do is go after road warriors and 
conferences. Maybe that's enough...

No, but I'm not privvy to what happens there.

I guess it would be possible to do some magic between the base station 
and the handset without involvement from the telco, but I'm not sure 
it's possible to make this completely transparent to the host.
