Propagating events through tree #67

Another question to do with a similar project to this. I would like to hook into React's event system to dispatch events (to begin with keydown) through the tree, bubbling from my target which in this case is not a DOM node but a custom React component that is backed by a scene graph node in a WebGL library, constructed similarly to the ReactART components. Because of this the target of the native browser event is of course not the actual target React component I would like to propogate from.
To dispatch I see I can do something like this:
ReactEventListener.dispatchEvent(EventConstants.topLevelTypes.topKeyDown, browserEvent);
But that leads to the ReactMount module attempting to iterate through the ancestors using a mapping to DOM nodes. Is there a suggested way to change this behavior so it can receive my desired target ReactComponent and walk up the tree from that instead, to execute the event handling?
