Re: Compression...

The other suggestion put forward - to use zlib - is okay, but doesn't offer very good compression. The advantage is that the library is installed by default on all Mac OS X systems, so you won't have to worry about that aspect. Personally I'd rather just statically link against the bzip2 library, but perhaps your preference differs.

If you're writing a real-time application, zlib is much, much faster than bzip2. Otherwise, I agree, bzip2 is a really good compressor.

Has anyone had any experience with 7zip/LZMA? (http://www.7-zip.org/) It looks Windows-centric and I have no first-hand experience with it, but it's open-source and their published statistics seem very good.

(I wrote drag-and-drop bzip2 and gz compressors for classic Mac OS, of course just piggybacking on the zlib and the bzip2 libraries.
Sadly I don't have the free time to write drag-and-drop compression programs in my spare time any more ;) )
