I didn't realize you couldn't do bind mounts read-only.  Interesting.

What about re-mounting the same block device (presumably as ext3) in ro

Or if that complained, maybe created an additional block device under
/dev with identical major/minor numbers and mounting *that* RO?

Maybe ext3 wouldn't handle that too well...
