I'm really enjoying reading this. I understand why it needs to be so long, but I think it could have more reach if there were also a short primer that succinctly explains why OSI is wrong, and proposes a single alternative model.
This PDF is an exerpt from the book Programming Distributed Computing Systems: A Foundational Approach by Professor Carlos Varela. He was my advisor at RPI, and one of the most pleasant professors I had the pleasure of interacting with during my time there. His classes were notoriously hard, but I enjoyed them very much. The full book includes very concise walk thoughs of various other less well known calculi and theoretical distributed programming models (in particular, the AMST lambda calculus actor model). If you like language or concurrency theory I highly recommend picking up a copy.
Bukkit was in fact preceded by hey0's mod, the project of a 15 year old kid who was largely responsible for bootstrapping the entire line of Minecraft server mod APIs.
After all these years though it is extremely exciting to see this advancement, I'd expect this to allow extremely large servers. Makes me want to start playing again ^_^
