WiFi helping people help other people to WiFi

Along the same lines as Marc’s WiFi w00t! post a few days ago, WiFi helped me help Nat to WiFi–across international borders, no less. I just received a text message from Nat in London asking if I knew where the Apple Store is in London: free WiFi is teh sux0r in London. I’d just a few minutes earlier managed to hunt down a smattering of free WiFi in Amsterdam. A Yahoo! search and texted reply later and Nat was on his way to all-you-can-eat WiFi from the Apple Store on Regent Street in London.
