This is a staggering amount of wheel re-invention...makes me feel relieved that we have HTTP so clearly dominant in TCP/IP land. I think Wi-Fi Direct is the way to go in the future. We've generally mastered TCP stacks and building an application that uses simple sockets is far less legwork than dealing with the intricacies of 30+ Bluetooth specifications. I should say I'm no expert on Bluetooth. Why do we still use it? Is it a matter of legacy or does it have some kind of killer feature that Wi-Fi Direct can't compete with?
