Have you tried watching the actual traffic that pd-gui sends to pd?   
Run pd from the command line like 'pd -stderr -d 3' and you'll see the  
communications between pd and pd-gui.  -d 1 would be one direction of  
that traffic, and -d 2 would be the other direction, but I forget  
which is which.

That way you can figure out which messages are the ones that you want  
to hijack :)
