• Creating games
• Joining and leaving games
• Creating and moving pieces on the board
• Extensive move validation (bounds checking, path checking, engagement checking etc)
• A customisable turn/phase system (this has been an absolute pain in the arse to implement – but it appears to be working as intended now)
• Full JSON messaging system (you talk to the server in JSON and it talks back to you in JSON, there’re no sockets, special protocols or proprietary formats)

The Google Code wiki is somewhat out of date (already!) as things slot into place during development, and I’ll update it as things become more solid. I’m currently using a private SVN, though as the project nears a working first version (and if there’s any interest) I’ll be happy to give access to the SVN – there’s a lot of experience and expertise out there, and I’d greatly appreciate a second opinion on aspects of the code!
