Amazon has just announced the beta release of Context Links, which will automatically link words and phrases to products on Amazon.com - complete with your Affiliate ID of course! This would be ideal for monetizing large content sites or blogs - without editing them page by page.
Log into your Amazon Associate account for details, or check out the latest on their blog:

I'd love to hear your thoughts - are you using it? Love it, Hate it?
