Again, not to be read as a personal attack, but your explanation is
not what I was looking for. It added very little to the description
I included in the first post.

Right. So basically you are saying that it's not possible to get at
the data anymore other than through direct device access.
Maybe this is something that could be considered for future XFS
versions? A tool that can ignore the zeroing-precaution and simply
give access to the data the inode points to, even though it would
not normally connect the two.
