True, and ZLib is found at every corner: VPN connections, various
compressed formats like NetCDF, and what else ? Here is a list:
http://en.wikipedia.org/wiki/Zlib#Applications .

Reversely, the Zip format supports many compression formats beside
Deflate (the one of ZLib): LZW, bzip2, LZMA... In a Zip archive each
compressed file may have a different compression format, which allows
for nice optimizations (this is what the ReZip tool is doing).
