Forum OpenACS Q&A: Response to ECommerce and Edit-This-Page

I don't see why that's necessary. After all if you're running an
ecommerce site - all you need to really feature are your products
and the product templates/product administration in the Ecommerce
Package can help you with that.

However, if you are running a marketing/ecommerce site - it might
make more sense to mount ETP as a separate subsite from ecommerce.
