If you walk in, WITHOUT a t-mobile/boingo client, you get our system. If you are a paid user of t-mobile, and have their client software on your computer, it goes straight to the t-mobile vpn/splash screen etc, same for boingo.... IE if you are a paid user on t-mobile or boingo (with their client software), you never see our site at all, it justs goes straight to their vpn. If you are using anything else, you go to our system.
If you have the custom software that only responds to say a t-mobile hotspot (like you have at starbucks), and walk into say a flying-j or ups store, you get nothing. If someone with flying-j software walks into starbucks, they get nothing. If either walk into a ups store, they get nothing.
Why would they want to use a paid service, when there are many that are free? Beats the heck out of me. I see it happen all over, especially here in Vegas, sitting at McCarren airport using the FREE WiFi hotspot (airport wide), and see some of the ummmmm ... common sense impaired... t-mobile/boingo users actually leave the airport with the free hotspot, get into a cab, and go elsewhere so they can use their t-mobile or boingo stuff. (To be fair, that was when the free site was new (first few weeks), now (in time for the CES), they have agreements with t-mobile and boingo to allow those people to use the free website rather than take a cab, and just go to their VPN)
