[snip] Koen, If I understand you correctly, the global model needs to register each app that connects to its signals, and then propagate those signals individually to each instance, while holding its updatelock, and then calling its triggerupdate(). My model doesn't allow direct modification of its data (all ops are through custom member functions to allow proper (hopefully) mutex locking). I think it makes more sense to me to add app* register/deregistering to my model and go from there. Would WCrossAppProxyModel need any sort of locking? Other than the updatelock, of course...
