Radamanthus, I just wanted to drop you a note to encourage you in your endeavor. I think this could be a great addition to OpenACS. Something like this could really help integrate the back office at a company that is already selling products, but also wants to sell on the web.
While I don't have any experience with the e-commerce, I liked where EC 4 was headed, as far as keeping the system very modular and easy to expand.
Of example, what if I was interested in using this system, with EC, but I already have a system tracking my orders and customers (as it runs the rest of my company), like Fourth Shift (http://www.fs.com). While I would not expect you to come up with an interface for such a system, it would be nice if the code was written in such a way that integration would not be an impossible task.
Keep us updated!
Sam
