Interchange is based on MiniVend and Tallyman.
I only ask because while ACS 4.X ought to include ecommerce, right now it doesn't. Since the ecommerce code was frozen at aD (and lord knows they could use some ecommerce right about now) is it complete enough to wait until it's available in OpenACS? AFAIK, OpenACS port was supposed to be out by now, too...
So I'm wondering what's more reasonable -- wait for the ecommerce module or just start using some other open source product?
