I thought someone a while back had indicated a semi-standard wrapper for zlib zip access in Cocoa. I might be misremembering.
Nitpicking. The CRC16 or more probably CRC32 are included in the zip spec's I think and have nothing to do with MacBinary. That might be added if you were supporting Classical era resource forks. For example a 3rd party shareware package called ZipIt used to encode the file signature meta information and resource fork data using MacBinary in the user field of the zip file header.
I did a classical zlib port for java that supported the ZipIt type files.
