Hi Santiago - Pd uses Portaudio to talk to CoreAudio. It loks like there's no reason one couldn't fix the code to offer multiple devices (although it still wouldn't work for Portaudio/ASIO because ASIO apparently doesn't permit it).
One reason I haven't done that is that Soundflower (if I understand correctly) does a decent job of it, probably better than I would be able to do, so I don't see an urgent need. (Also, allowing multiple devices complicates the code and can easily introduce problems; I've spent a lot of time fiddling with multiple-device support in ALSA and MMIO and have come to feel that it's an endless time sink.) cheers Miller 2002 when multiple devices weren't allowed (as far as I know).
