Um, how is this mutually exclusive?  My motivation in working on pd- 
devel is unchanged.

 From what I gather, Miller is more or less game for including that  
work.  My plan is to spend June and July working on Pd-devel to get it  
to a fully usable state so that we can discuss it at PdCon.  I hope  
that others will join me in that effort.

In particular, I want to structure the code around the idea of a  
communications API that uses Pd messages for both directions.  For  
now, it will use the existing pd<-->pd-gui API, then the next step  
would be working on the C side of things once Miller has included it.
