Exactly. Capturing would need support in the function that receives the 
packets from the device - same for raw sockets, though.
Ie. the logic could look like this:

new packet
        is there a packet monitor?
                yes - clone data for that monitor
        is there a handler?
                yes - deliver to that handler
                no - deliver to raw link sockets

The amount of work should more or less be the same I guess.
