You may be right, but i would guess that the key creation process will stay nearly the the same in alpha,beta and final version. I plan a package that will enable everybody to create this vouchers and as i am not a pro dev it will take some of my time. The key creation process will hopefully not change that much so it can be prepared now which will give me some more time for the graphics later on and i will be able to test my first results on the beta.
