Nice work. Kinda opposite of me, never did networking but always rewrote and created content or did clientworkWell, I don't really know yet. I'm really enjoying writing some of this code - Much of it is new to me, I've never got to do a lot of hands on with networking, and building actual structures that require planning and refinement to a level that isn't trivial.
I can only imagine writing actual content will be the death of me, but I don't know. If I write a flexible, clear enough API maybe it won't be as difficult as writing content in Dementhium? Who knows.
As for releasing - Sure I think I will release it. I've just put up the link a few hours ago to my progress thus far
EDIT: Just broke into something pretty great. Dementhium as the Mob class, and Player extends Mob, NPC extends Mob. I just made Persona extend Mob and Player extend Persona, where Player is a client and Persona is a dummy player that has an update mask, a name, a profile/account, but doesn't do anything. Now I wrote a quick test class which gives the Persona an AI - Okay, it's only one that follows you around mindlessly, but, it's a step in the right direction of bots!
