I already said it on Twitter. I love this!! Having a server side implementation is awesome and exactly what I needed for a current client project. Just bought a license as well.
A little side-note: I think it’s brilliant that more and more Kirby plugin developers go for the moral license. But please keep in mind that this model has its limitations. So far it works great for Kirby, but it only works because of Kirby’s main target audience is a very professional and decent bunch of people 
I’m not sure if this easily scales to all plugins though. I’m more than happy if it does, but don’t feel bad about just taking money for something you spent time and knowledge on in the old fashioned way. Many people forget how much it takes to maintain and support code you put out there. Building something is easy. Taking care for it over a long time is not. Kirby is getting better and better with all the available plugins out there. The more sustainable those plugins are for their creators the more other users can rely on them. I’m a huge fan of open-source, of sharing knowledge and code, but we should never forget the people behind the projects we build upon.
