One possible scheme would be to store the file info compressed, this
might be a smaller impact than rewriting the protocol. Typically gzip
gets 3x compression on ascii, no reason why this couldn't be accomplished.
It would slow things down so would need an option to enable. This would
work best with streaming compression rather than gzips block-oriented style
else every entry would consume the minimum block size.
It _is_ a hack I admit...
