Hmmmm It would seem that in order to sell Internet connectivity one must be connected to the Internet. If you feel that Internet Connections can't be sold over WiFi I would ask you to prove that. I just checked in to my Timeshare Saturday and found seven different clouds to connect to so there are some people that believe there is a market.
These folks did not have to establish the Internet connection as it was readilly available from the local telephone company, where as these folks seem to have nada connectivity. I'd say that this might be a good market for all the services that can be offered by NMC wouldn't you?
