I noticed a lot of categorized resources to products, etc, from the apple.com site. Do you have to have some kind of deal with them to be listed there, or is there some way you can tell them about your product to possibly be listed? It seems you would get a lot of exposure there as it's the default page for Safari.
I think the macintosh product guide is different from the downloads that they also list. So you probably want to check this out as well: http://www.apple.com/downloads/macosx/submit/
