On a recent episode of Farscape they were orbiting a Saturn-like ringed planet, just "above" the outer ring. It was a lovely special effect, which leads to an idle question:

If we were in a nice spaceship near Saturn (in our solar system,) and we decided to orbit from above the outer ring, so that we were gliding above the ice and dust of the ring, how clean would the space be above the ring plane? How close could we get? Is there a sharp demarcation between the ring debris and the space near it? Just a thought, (in case I want to open a floating hotel with spectacular dining hall views of the rings from above.) [img]/phpBB/images/smiles/icon_smile.gif[/img]
