This is my understanding as well... :) I tried to make Pd into a true callback application a few months ago, only to discover that it made no real improvement in the APIs that ewre supported then. If it turns out that pd/jack actually performs better using true callbacks I might reconsider and make the change.
Putting audio in callback routines in Windows seems to be out of the question since callback routines can't make system calls in windows.

I dont know much about pd and jack, but I was told that if you run jackd as root then you have to run pd as root as well, and same for non-root, but it seems redundant to run pd in realtime and jack in realtime. if pd is connected tojack and jack is running in realtime, then shouldnt pd be inrealtime as well?
If I understand correctly, PD is not a textbook Jack application - it doesn't simply register a callback function that Jack can call. Instead, it has its own main loop that processes the audio stuff, and that's why it needs to run RT. I suppose that there is a Jack callback, but maybe it only copies buffers from PD to Jack (or something like that). Hopefully Miller or someone else will correct me if I'm off base on this.
