Indeed that would be way cool.

In playing with chaper tracks in Rev I've found that while Rev is normally
good about displaying the appropriate controller for each QT type (movie,
VR, streaming), with movies that contain chapter tracks it doesn't seem to
show the chapter pop-up control.  It'd be nice if Tuviah could add that
along with at least a read-only property to get the chapter names and
corresponding timecode offsets.

Since you seem to know your way around QT, maybe you can help me find
something:  I'm trying to determine if it's possible to have a QTVR movie in
which portions of the pano have animations looped in it.  I'm told that
LiveStage Pro can do this, but in playing with the demo I can't figure it
out, and I've not seen any good demos that show such a technique.

Is this doable?
