It's essentially the development branch of Pd-l2ork, so it inherits all of 
its benefits-- infinite undo, native state-saving, GUI theming, and so on.
As for evolving-- you can have a look at the additions I've made to data 
structures to see.  With 15 objects one can make a scalar knob that rotates 
between 0 and 360 degrees.  With maybe 5-10 more objects one can have 
multiple knobs with changeable symbolic names.  Compare that to > 700 
lines of C code in the knob external (plus the occasional tcl error, "can't 
create" error, etc.)
 
There's another possibility which I haven't explored-- that is, you can load 
anything created with an HTML5 api into the Purr Data GUI and send messages 
to Pd from it.
 
As far as Pd<->GUI communication, I removed most of the tcl commands from 
the C code and replaced it with a parameterized interface.  I'm still leveraging 
the same socket-based communication.
