One approach could be use an online markup and approval tool, where users can all view the same version and make comments. We have a tool in beta called MediaMarkup, see www.mediamarkup.com. This will allow you to upload single or multi-page PDFs for review. Users comments will all be within context and on the same version without emailing files around. Multiple approval groups can be setup so you can get different users in each group to make related comments, eg from legal & marketing etc, so they can see discussions that related to them.
