right.

It woudl be trivial it add something like
<setScenelist id=/string/>

and let piave handle more then one scenelist. You could then send scenelist 
id="clip" and id="main" ot whatever. This way you would not need three piave 
processes.

ok. And also I am not sure, we need to flip each time focus changes. the only 
relevant thing is "play". just scrolling is not such a big issue.
