It sounds like the rsync compatible version of gzip (there's a patch 
floating around; it's part of the stock version supplied for Debian 
systems) would do what you want. It compresses the data in chunks, 
periodically inserting a new compression table, and undoubtedly a header 
structure that could be used to reestablish sync after a chunk was 
corrupted or lost.
