I am no expert on the subject but when thinking about the implications of WIFI and the improved performance of the hardware (reach, connectivity, interoperability), I can't avoid thinking of a community of WIFI equipment owners (individuals not operators). If a community develops and an agrrement is put in place, the whole community -if geographically seamless- could share freely its resources between users as long as each member has the capability to re-transmit other users data. This would in fact make mobile operators obsolete and people would then be able to "talk for free".

Does anyone here know of any such iniciative in the world or any practical example of this? Is any such community developing?
Thanks!
