Hey, let's sell a service that uses other companies infrastructure! A great way for WiFi hotspots to close themselves off with password only access!
Already happening. As I noted in another thread: Having a WiFi-only tablet has proven very enlightening. In the three months my wife and I have had our tablets, our experience is there are relatively few wide-open WiFi hotspots anymore. The ones that aren't locked-up with at least WEP have HTTP-based username/password auth. systems.
Interestingly enough: The few we've found that were wide-open performed terribly.
