If the python stuff is only for the gui and non-realtime stuff, this is a very 
practical approach. There are quite a few people doing that. I believe Fons' 
session managment and assorted apps are running that way (altough he doesn't 
seem to release them). Some of my prototype apps for the next-generation 
JackMix are built that way. And I would have done this for my university-job 
project had I learned python earlier.

Doing applications in python with the sound-stuff happening in a separate C-
compiled thread) gives that advantage that you can implement the apps as 
modules and run them either stand-alone or within a bigger controlling app.

Have fun,
