such things are available commercially; I can't say how well they work.
personally, I doubt that this kind of thing can be done well at a purely
block level - I think that some file-level information would be beneficial,
perhaps essential. but this is a layering-violating idea, and seems to
rub a lot of people the wrong way. on the other hand, there is a seperate
movement towards "object storage" systems, which is certainly a related idea.
