Zun Tzu?

Has anybody out there used Zun Tzu for online games? Esseentially its a jazzed up verison of Vassal which looks really nice (see screen shot of a Battlelore game below) buy as its a newer version it only has about 100 game modules available instead of Vassal's 400+ (and they seem mostly to all board games too, vice miniature wargames). I'd be interested in any feedback on this one - cheers! http://www.zuntzu.com/index.htm
