Also, occasionally I'd like to turn on/off one of the VTP files (or the 
objects its contains). I know the Paraview supports this for PVSM files 
but I'd like to do this with PVD files, because I'd rather not write a 
PVSM file (they're horrendously complicated :-) ).

PS:
In case I do need to write a PVSM file, I'd like to know if there's a 
minimalist version that contains only specific stuff like while Paraview 
defaults to the unset parameters. For example:

<ParaView>
   <ServerManagerState version="3.0.2">
     <ProxyCollection name="sources">
       <Item id="4456" name="Stuff.vtk"/>
       <Item id="4455" name="More_Stuff.vtk"/>
     </ProxyCollection>
   </ServerManagerState>
</ParaView>
