My guess is that it'll have to be a combo of moving Pd 0.43 to the DD  
approach and rewriting the DD code to fit into 0.43.  It sounds like  
you have 'pd-gui' saving the file using Tcl code.  It should be  
possible to port that saving code to C and have it part of 'pd', and  
that would then fit into the existing code much easier.

Would the easiest first step be writing a single, complete escape  
mechanism for the pd <--> pd-gui communications?
