I've written a new IO module for OSX, which is to replace the  
coreaudio module. It uses the AuHAL API of OSX.
The main advantage over portaudio is that very low latencies can be  
achieved (down to 16 frames).
It's experimental at the moment, but hopefully will be fully tested  
for the next release.

-+rtaudio=auhal is the option to enable it.

Two caveats: 1) only OSX 10.6 and above  2) output device selection  
only works via OSX sound preferences
at the moment; input device can be selected using -i adc:   
where  is the device number
as printed in the csound console.

in GIT now.

Any chance you could point me to the location in the Git tree? I
need to rewrite the OSX output routines of sndfile-play (which is
part of libsndfile) and this might be a good introduction.

Cheers,

Yes, hopefully by end of today I'll have something posted here. :D

I think something like this should happen for Windows too. ASIO is
great, but it doesn't support full duplex audio.

First time I heard of it. Back in the day, when I used Windows ASIO  
did full duplex OK.
