Until then, there is Moon Zoo.
It's like Google maps for the lunar surface. Their mission is to help scientists measure things like the age and history of the moon. They do this by having users like me and you check out detailed pics from the moon and point out particularly big craters. Apparently you can tell a lot about a place by the size and number of craters it's been hit by. If you are lucky you may even spot some old exploration gear left lying around.
Sure, it's not as fun as bouncing in a low gravity environment will be, but for a space buff with some time to kill, it's a great way to feel a little closer to the final frontier.
