> this is best done in a way that can be switched off by the users. At the application layer. I totally agree, but again, application layer will be limited to application servers.

It does not allow VoIP calls according to "operation license" which is based on city, state or region regulations .. my suggestion is that the tower moves not the user.. search for mobile BTS. It happens in certain occasions where hundreds of thousands of people head to the same area at the same time to attend some sort of event, so operators move mobile BTSs to the location of the event for a day or two... in this case the operator needs to put configuration that reflects the agreement with the state/city or region .. it could be much easier if geo-location is involved in the game, not at the user's end but only between routers. > I'm not sure what this means.

I'm sorry, but again going to suggest that application layer solutions, e.g. > configuration settings by the ISP on each of its routers, would best be used in this case too. Nope, I am assuming that the operator could manage bandwidth based on estimated population, static configuration on the router would be ideal if the router is fixed, but what if the router is mobile.
