Looks like a really cool idea but there are two things that come to mind
1. WTF does this only have unprotected wifi or can you add a WPA key because if not everyone will be able to connect and see your files. "maybe I missed that skipping through the video"
2. I see someone flashing this thing soon and turning it into a nice web server that has a wireless log on page perhaps that says login to free wifi with your gmail or facebook account and save all passwords to a database. This is just a quick idea I had but I bet you could do a whole lot more. I can't wait till the someone starts messing with one and comes up with some crazy idea to do with it. Should be fun!
