BBS, Lua, Coroutines: Part 2

Regarding FSM's, remember that you often can split them into several FSM's if they get too big. That reduces complexity immensily if possible.

With regard to scaling coroutines, I guess this is basically the problem that Erlang tackles. Having zero shared state obviously solves the migration problem. (but raises other challenges)

Lua and BBSs? Awesome. We ran a great, well, we thought it was great BBS back in the day :)
