I would use the devfs device registration mechanism to trigger an "arrival" event. Conventional media would "arrive" as well, then (it would just never depart). Arrival would trigger a "mount" internally to a POSIX namespace accessable by root. Devices with removable media would "arrive" before their media did, and when the media showed up (was inserted) would fall into the physical to logical device translation that gives us partions and slieces and media perfection and compression... etc..
