I've just been awarded a grant to bring the web monetisation APIs (https://webmonetization.org) into Moodle through a suite of plugins. My hope is that this will massively reduce the barrier to entry for people wishing to build business models around their content and make buying such content easier and safer for the consumer. The plugins will allow entire sites, courses or individual activities to be monetized via this new browser API. I'm really excited to be working on this project and would welcome input into the evolving architecture and design of the solution as I work on it from anyone who has an interest in being an early adopter.
