Support additional use cases

I'm currently at the Drupal Commerce Camp in Switzerland and we're discussing how to use user points as a virtual currency and integrate it nicely with Drupal Commerce.

Your module is a nice starting point and supports one use case that I haven't thought of, but I would like to support at least two other use cases. Maybe in separate sub-modules or maybe even as separate projects. We'll see about that.

Here they are..

- Allow to set a price of a product in points. We're still discussing how exactly to do this, but maybe we could create a "Userpoints" currency and a corresponding payment method that is automatically activated when that currency is chosen. I need to talk with the Commerce Guys here how this is best done. This is for cases where you for example either only want to sell a product with userpoints or for a different value (e.g. 10$ or 1000 points).

- Revert the whole thing: Create a "Userpoints product", that allows to buy userpoints with real money. This could for example be done by adding a special field to the Product that contains the amount of points that is granted when this product is bought. The points could then be used as a virtual currency on the current site, e.g. 10 points to create a node (userpoints_nodelimit), or gain access to a node (userpoints_nodeaccess). Or alternatively, say that 1 product = 1 point and allow to buy 10, 100, or 1000 of that product.

What do you think?

Interested in implementing/supporting/maintaining these use cases with your project? I would help of course..
