I'm working on a site that will require user subscriptions. I don't see it as a built in mechanism (hopefully I'm just missing something). My thought was to basically create a user role that would also double as a product.

The shopping cart webpart does most of what I need for this. It creates customer and user accounts, which is perfect. And the built in page security handles the lockdown of pages...I guess I'm just wondering if anyone has any thoughts or advice for how to create a product out of a user role?

Or maybe I should just update the user role in the payment gateway...

Any thoughts, ideas or feedback would be great :)
