We are in desperate need of a payment gateway implementation for the GoEmerchant.com direct gateway (XML based, their oSCommerce example looks to be adapted from authorize.net) and we also need a modification of the userpoints integration.

For the userpoints integration change, most of our products are digital downloads, but we also offer subscription services, we plan to offer "bonus points" to our paying subscribers that could be used to purchase our digital products, but we need to prevent users from using points to buy the subscription services.

We would like to be be able to define which products could be purchased with points and cash, with points only, or with cash only. If this could be done on a per product or per category basis we would be golden.

I envision a two check box section on the add product page:
[ ] Product can be purchased with Points
[ ] Product can be purchased with Cash

If both are checked both methods are available, if only one, then the purchased would be limited to only the correct payment method.

Any interest?
