I don't know, if the plugin layer is completely ignorant of full duplex applications. Maybe there's just one little thing missing in the whole picture: A plugin somewhat similar to the multi-plugin that knows how to combine writable and readable pcm devices into one writable/readable one. Another approach would be, like you said, to create a virtual soundcard that does nothing else than providing sw mixing for another "real" card... I'm not a kernel hacker, so i don't know anythig about the challenges of creating such a driver. I assume that the first way is easier..
