Chinese Chess

I'm enjoying playing International Chess like this on a website, but I wondered if anyone knows of a similar Chinese Chess version? Preferably one which also supports westernized symbols?

I must admit, I've even had a look at writing one, but the move validation rules confuse the hell out of me...

I suppose that alternatively, does anyone know of how you validate knight moves in Chinese Chess using bitboards, as knights can be 'blocked'?

http://www.itsyourturn.com/ has a whole bundle of chess variations, including chinese chess.

(Chinese chess playing only, in language of English and Chinese.)

or perhaps one day here at RHP?
