Mixing these two in the same interface seems like a really bad idea.
The input layer is the right interface for devices that directly produce
events. If you want to decode them in userspace you need a different
interface for the daemon. Not sure why you really want to do this in
userspace, though.

The input layer also does some outputs, like the pc speaker :)
