At least for PP it's quite straightforward.  I implemented a couple
slave commands to control the pp and scale/expand filters dynamically
for a project I'm working on.  You can see the patch at
http://sault.org/mebox/downloads.php.  The scale/expand stuff is
terrible, but toggling pp during runtime is trivial and useful.

Cheers,
Jason.
