At the moment there is really not support for it. However, the initial
plan was to support this. The GnomeVFSVolumeType type
GNOME_VFS_VOLUME_TYPE_VFS_MOUNT is meant to be exactly this. I planned
to add some sort of module support so that you could write code that
detects plugins of a device and automatically generate a VFS_MOUNT
volume object at a specific uri and tell everyone about it. The
detection plugin would run in the vfs daemon, which has a nice
environment with a guaranteed mainloop etc.

I don't think anyone is working on finishing this at the moment, but I
don't think its much work if someone was interested.
