That's a cool thing to know, thanks. You could definitely do some viral marketing this way if you were more devious than I.
The SSID in your viral marketing scheme would have to lure people into connecting to it while at the same time advertising your product.
Sounds hard... anyone have any ideas?
You're riding the fence there. 'Luring' people into connecting to a network where private information will be readily accessible is (even if just for marketing purposes) very, very sketchy. Especially if you're using a deceptive SSID. Just a bad idea.
I think it's just best to leave it as a network issue and not try to force advertising campaigns every nook and cranny as possible. That includes broadcasting domain names using a poorly designed network identification method.
