Hey Jonathan,
I'm cc'ing pd-dev since this is a topic that could interest others and  
others could contribute to.  I've started a private git branch of  
tkwidgets that I intent to push once I get somewhere with it.  The  
idea is to try out a new idea for how GUI objects can work.   
Basically, I think I can make it so that Tcl handles more of the  
interaction with the user, minimizing on pd-gui <--> pd  
communications, and making it easier to write GUI objects.  Its not  
trivial to do, but should be doable.
