eMaksut is a sister/child payment service of Maksuturva. eMaksut payment is technically almost identical to Maksuturva, but eMaksut service doesn't keep track of delivery statuses and doesn't keep merchant's money pending based on delivery / client response. It is more "traditional payment service" in this fashion.
Commerce Maksuturva module has already some preliminary options to choose eMaksut instead of Maksuturva. These features are still untested and are likely to need some further development. It may require some architectural thinking aswell, what code should be shared between these two services and should we move Maksuturva delivery stuff to additional submodule.
Patches or ideas welcome.
