Sounds cool, I used to play an PBM (Play By Mail) game called It's a crime... been waiting for a modern version of this since forever.. (http://www.kjcgames.com/crime/index.php)
If you would be amenable to it being realtime and not play-by-mail, I could send you a tweet with the source and demo (which will be running a live version and won't be closed (assuming I don't become homeless and run out of money for hosting any time soon =) )) link for you to take a look at?
