This would be nice.  Terry Lambert mentioned that he had implemented a read only
version of JFS, perhaps this would be a good start?

Does JFS also use linear directory structures though?  I noticed while reading through
some docs on XFS, that it implemented directories as b-trees.  Im not quite sure how
one would implement this, but it sure seems like it would be a win..
