Is this a good way to package a multimedia ebook?

Hi gang,

Quick question: I'm trying to create a multimedia ebook that would include several sound files throughout the book. I don't have Acrobat, which I understand has the capability to embed the audio directly, and so I've been considering alternative methods. So far I've had no luck finding a reliable but affordable software solution, so I'm thinking of alternatives. I'd like to know what you think of my solution, and/or if you have any better ideas.

My solution: package the ebook in a zipped folder. The folder would contain the book as a .pdf, and a folder, called something like "Sound Files." The .pdf would contain links to the individual sound clips via RELATIVE paths, so that, as long as the user kept the files in that structure, they would work.

I realize that many people probably throw all their ebooks into a single directory, which would break those links and make this inconvenient. However, those people could still access the sound clips on their own, wherever they do store them. (And I'd make sure everything was clearly labeled). Still, this seems to be the cleanest, most convenient way to work it for everyone.

(I should add that I'd rather not link to online sound files, whether on something like youtube or my own server. I realize that those links would never "break." However, I'd like for the package to be self-contained and not rely on an internet connection).

Any thoughts? How do others do something similar?

Thanks!
