Our company added MultiPeer Connectivity to the i Phone client of Whoopee . We added already WiFi Direct to the Android client of Whoopee . Both features are not easy to manage. I wrote about the headache of WiFi Direct . MultiPeer Connectivity has also some problems about session. It doesn't work properly when lot of peers are trying to connect. and when working with WiFi bonjour. According to the both experiences of WiFi Direct and MultiPeer Connectivity, the latter is somewhat convenient for programming and also using it. MultiPeer Connectivity provides all APIs for searching, connecting, sending, and receiving easily, the error rate of searching and connecting is very lower than WiFi Direct, and there is happily, No System Dialog!!! I think WiFi Direct is little short for commercial products than MultiPeer Connectivity.
