If I knew how to do this correctly I'd be earning a lot of money... :) Truthfully this is work for at least a good two weeks of designing, likely much, much more... to just determine the very basics. Even assuming you already have good fast compressors/decompressors which run in neglible time and achieve the best compression ratio on the market - it's still very, very non-trivial to make a compressed random-access read-write filesystem out of that. Some files should be compressed max, some only slightly, some not at all, this should all be user selectable on a per file (or even per file section) basis and the default should allow the file-system to learn which files to compress and how-badly... etc. etc. The file-system has to auto-defragment and it has to minimize fragmentation in the first place.
Cheers, MaZe.
