I once tried to do something similar like this. I use a C++ TUIO client library from reacTIVison [1] to build a multitouch application. The library spawns a new thread to receive input from a multitouch device. I originally processed the events immediately when they arrive and then made some modifications to the scene graph. But, my application crashed many times and it was very difficult to track the problem since the error started from OSG part, not my application. Then, I tried to buffer the incoming events and process them before I call Viewer's frame(). As a result, now my application works fine and never experience the same problem again.
