So I've taken to wrapping this logic from a while ago from within a browser cookie that can only be set by logging into the admin to set it. I have some fun hacks to the front end now that add admin functionality but they generally would rely on this sort of "inserting-admin-stuff-into-catalog-side-stuff" being PCI compliant. I was wondering if it'd be possible to do so as an add-on, which I could then make a dependency of other add-ons. Any thoughts on this?
