I believe you can create compressed .DMG archives. If you have already done this then zipping won't compress further. If you haven't but the content is compressed files then zipping or compressing won't help.
I was going to suggest [Split & Concat|http://www.xs4all.nl/~loekjehe/Split&Concat> but I see its Leopard status is uncertain. There may be other similar utilities out there for which you could search.
