I hope there will be a way to manage the bandwidth and load properly. I think it will be a critical point for this project to be successful. If, e.g., I have an open wifi network access point in an apartment complex or even neighborhood, without the ability to manage bandwidth it might lead to a freeloader problem.

I am thinking it would be cool for local access point owners to, through the router, network and set bandwidth policies as a group. That way freeloading could be mitigated by throttling bandwidth to encourage people to add nodes. It would need to also maybe support lightweight communications protocols in order to facilitate coordination and maybe messaging to people connecting to the open wifi access points.
