Dear Prof Reed, First of all - I need to thank you for taking your time for responding to this thread. Thanks When I meant rate-limiting - I meant that if access points are only allowed to support say x%of the unused capacity available (FON does similar - it allows only upto 512Kbps) -- but at Less-than-Best-Effort to access only essential sites - no youtube/facebook - but national health service, government forms, wikipedia etc and probably support vital sensor/video data transmission with several offloading/onloading methods..When the paid user comes online and starts using all his capacity, then ofcourse the free user does'nt get anything until he finds another access point to piggyback on.. The notion of CCN would make access to content better by caching @ the edges.
