I gotta say, that's pretty hot.

Very interesting technique!  That's a good one to know.  I don't  
think I would have thought of that.

For what it's worth, this "starting simultaneously" issue is  
something I'm working on.  The ill-fated release of Video Cue 1.1.5  
was intended to address that, but clearly it gummed up the works and  
had to be rolled back.

BUT, I'm in conversation with a guy from Apple to try to figure out  
the best way to do this, so hopefully I'll be able to make progress  
on it.


Anyway, thanks for the report.  I don't suppose I could persuade you  
to write up a showcase on this awesome project, eh?  :D


Cheers,
Chris
