Yes, it is cool. And you don't have to wait 7 years. Cassini already completed a trans-ring intersection on it's breaking maneuver when it arrived at Saturn. You can probably find videos on the Net. There are some awesome high-res shots available. Go and find them.
The fear then was that a mis-calculation might be the cause of the worst man-made environmental impact in the solar system -- crashing into the rings and disrupting their delicate balance, causing them to collapse into the planet. Of course with it's tiny mass the most likely outcome would have been just losing the probe as some chunk of ice smashed into it, even with the high velocity it had on it's way from Jupiter. Now presumably the probe's velocity is even lower, so it should be okay.
