Being a zaurus oldie (owned the very original model from the sharper image in the early 80's I believe) before the newton, cassiopeia, iPaq etc I am looking to come home for my son. His needs are simple which the 6000 or 3100 fit except for 1 uncertainty...will a zaurus device run the java enabled web based game runescape ( through a browser?

If yes, what do I need to do or add to get it working or will the netfront browser handle it?
