Product with multiple file types AND multipart download

[robgnyc]

Is it possible to set up a product which is offered in multiple file formats AND each of these file formats is a multi-part download?

I've seen tutorials that cover one or the other of these but not both and I'm wondering if I can combine these somehow using attributes or if I have to create a subcategory for each file format and then multiple attributes for each download.

For example I have Product A offered in format 1, format 2 and format 3. Each format is broken into download 1, download 2 and download 3. They cannot be zipped into a single file.

How would I set this up?
