I had the same idea (as have others). I think this is _possible_ on _ALL_ fs types that are writeable (how to handle a CD-ROM?). NFS wouldn't work though (or could it?).
The tag could be put in the superblock where possible, or a read only (hidden?) file when not. A tag could be as simple as an 'int'.
I think this would mean changes to the 'mount' utility and fstab format though.
