Interesting. Is it using WiFi Direct or is it just a standard adhoc WiFi network? I though WiFi Direct was suppose to basically be a the open/standard transport part of Airdrop like things such that it would be seamless but frankly I have not used it enough to know.

I'm also a bit surprised QR codes can't be composed or combined. e.g have a single QR code that has a WiFi connection as the first code and then a URL code as a second. I know QR codes can increase in size to fit more data but I guess it still has to be a single string/byte array?
