Although I don't know Python, I have read enough about it to know
it fits well with the kind of job. I suggest using python-inotify rather
than piping inotifywait to your daemon. I think it would be better
because it is not so easy to manage a pair of daemons: when you kill
your automounter, the associated inotifywait is not necessarily killed
in the same time.
I also suggest you create the mount point in /media for unknown
media. For the others it could be listed in a config file containing a
list of (uuid, mountpoint) pairs.
