This would be scripting of Kdenlive functionality itself rather than piave, 
the idea would be to allow (power) users to extend the functionality of 
Kdenlive.  The end result of a scripted operation would operate on Kdenlive's 
document model (which get's translated into veml when passed to piave) rather 
than on the veml directly.

The advantage of this is that the end result of a script can be edited by the 
user from within Kdenlive. If you were to run a script on VEML (and I see no 
reason why you shouldn't be able to do this either) then the result would not 
be editable from within Kdenlive.

Another advantage is that you could script other parts of Kdenlive other than 
just the timeline - for instance, manipulation of any project management data 
that gets added to Kdenlive.

One advantage of being able to script VEML directly is that you would be able 
to write scripts that access functionality that exists in the renderer 
(piave) that is not natively supported by Kdenlive.

Cheers,
Jason
