Apologies to Linux people for the MS-DOS and (even worse) OS/2 references.
Please delete these in followups (since they'll be in comp.os.linux).

Has anyone done or looked at doing this for Linux? I know a guy that did
some research (incl implementation) on compressed file systems; I might
see if I can get him to copyleft it and let me port it to Linux (if I can
find time; probably in a few weeks).
