I also wanted a way for people to go on and create their own plugins and be paid for their work - so as you create plugins you're able to add them to the marketplace for others to use for free or to 'subscribe' to them for a max monthly rate that is applicable as long as an application is running. The plugins are go-code, and when you apply them to an application and deploy it, it's deployed into it's own isolated machine from other applications - running native Go code.
If anyone is interested in helping me test this, please send me a DM after signing up on the site and I'll approve your account and set it up to bypass billing during testing.
