The FS layout policy and directory entry management policy are not very seperable from gross hierarchical block management policy in the current VFS implementations. So it would be more than a little work if you attacked it directly, and didn't want to end up with a royal kludge. If you attacked it indirectly, by seperating policy implementation, it would probably be about half the work, and then you'd have to pay the other half of the work to get your changes checked in. If you need something fast, I'd say "kludge it and label it 'KLUDGE' in big, bold letters".
