- This isn't *really* a cheat, but: have you considered building a permanent
- dictionary, or dictionaries keyed by file "type"? Mod a compression routine
- to load a dictionary from a separate file identified in the compressed file's
- header, rather than storing and loading
- a dictionary from the compressed file's header. Periodically, run a
- compression
- program on the set of files kept compressed, to see if you generate a new
- (and better) dictionary, and either keep that for future use or use it
- to convert the older compressed files. If your files are being compressed
- and uncompressed at different locations, this means periodically transmitting
- new dictionaries.
