Interesting. People putting lots of data in one file not spraying it
around the disk is a big help here anyway. The kernel (and other non
Linux ones) generally know a lot about the idea that files are related
data, less about directories being so.

On disk blocks you can ask for the block numbers of the entries to a
file - used by boot loaders also useful for analysis (FIBMAP)

As to the ext3 rewriting on the fly, its doable given some space and has
"PhD or masters" written all over it if you can find the right

Executable compression has been tried - but since 1Mb or 4K cost about
the same to read off a modern disk its not been shown really useful (at
least so far).
