Hey contact me, I am doing something at the moment (ok this next few weeks) from cental whangarei. Using a cental db to enable roaming over spots etc. If you have your own basic gear we could add you in (our central db for access control) and let you earn something as well (well assuming someone wants to access your spare bandwidth). Want to play?
The idea is for each hotspot owner to earn proportioan to what clients have used. So for client x who pays for 1mth access at say $40, and who uses 60% of their bandwidth at hotspotA and 20% at hotspotB and 20% at access point C. The income would go 60 to A 20 to B and 20 to C. All central control for payments (captive portal) and remembursments. The more hotspots the better.
