I'm using HTML in my product descriptions, and I want to be able to use a hyperlink, not just a related product listing, in order to redirect clients to another product. Reason could be things like upsell, picking components for a multi-component product, etc. In WordPress, you don't have to use a full URL, just a relative page. This would allow a photographer to have a product listing on her or his Web site with a link that would take you directly from the site to the product in IBY to actually order. This is how ROES works in conjunction with labs FYI: labs have large product listings online with descriptions and links to the correct item inside the correct catalogue.
