New Multiplayer pure java Game engine SocKit

Introducing ‘SocKit’ A Multiplayer Engine for Turn Based Games
‘SocKit’ is a complete solution to build multiplayer turn based games, removing all the complexity of network programming and turn management, allowing you to focus on your game logic and design
I’ve spent three years developing this game server and client libraries. I’ve even built a complex poker game to test the API and help enhance it.
Take a look and see if it fits your needs. I would appreciate any feedback or suggestions.

and ended up with a similar architecture.
