Hey you guys should check out InstaWifi. Its a app that lets you setup a wifi connection via QR code or NFC tag. I could see this being useful, especially for me because the key for my router is very long and I always have to look it up!!
Edit: I should also add that I am going to a 4G area tonight so I am excited to see what speeds I can get and how the perofrms with 4G!!!
