Battlegrounds RPG Edition

   My buddy sent me a link to Battlegroundsgames.com specifically regarding a what appears to be some kind of universal RPG engine that it says will accommodate any system. With it, you can download all sorts of nice looking maps, virtual miniatures, etc. and play you game of choice with anyone else, anywhere else, on the internet. My question to all you computer geniuses out there (I am a computer-idiot...sigh): has anyone tried this thing? Ever even looked into it? I don't know enough about this type of stuff to make an informed opinion, but to me it looks kinda cool. Any opinions from those who know better would be greatly appreciated, thanx.
