We have started working on this new feature already yesterday, and we have decided to use the new API of 2Checkout for dynamicaly defined auto-reoccuring payments, not even needing anymore to setup 2co products. I will probably PM you later today with details.
Awesome, you rock! Let me know whatever you need. The automatic updating of credit card numbers that expire, replace becuase of being stolen, etc keeps 2Checkout way ahead of the others for recurring billing right now and will dramatically change things for me.
