Anyway, it's a different thing that will have to be designed and considered carefully, and that design doesn't have a whole lot to do with this little driver here, except insofar as it could build on top of it in one way or another. Yes, it's an important thing to do. No, I'm not going to do it in this patch here. If you want to have a discussion about that, start a different thread. Thanks, Jason
