A lot of details still need to be tested and tried as you can see. General vision is that vendors would be able to create both subscription and one-off payment listings and price them as they will. We will be reviewing subscription-based products (we have to, since we'll be processing payments and dealign with potential refunds). We would deduct a commission according to our costs (review and payment processing) - we don't intend this to be a for-profit component.

So, most likely every subscription see more would be added to the subscriptions package and billed monthly to keep it simple and bundled.

Transfers are much easier with subscriptions - the new owner just re-subscribes to the same modules and carries on. No need to worry about individual licensing terms of every module that was purchased one-off (some do allow transfers, some don't). For example, Trident handles modules in a way that data is retained when you deactivate a module, so you can re-subscribe to the module and the site data associated with it would still be there. DolphinPro will be the same when subscriptions come.
