Steven,
I've investigated this further and you're right about the transition callbacks not getting called when you attempt to transition the same node multiple times before it completes. It actually behaves very odd :-/ I'm not sure the best way to deal with this, but resorting to a queue looks like it will be the safest thing to do. The drawback to the queue approach is that things will have to wait until the current running transition completes before jumping ahead to the latest item added to the queue.
It doesn't look like I can get this in for PR3, but I'm still shooting to get a solution in for GA.
