    I had started a program to do something like this, but eventually I fell behind on it. The goal had been to allow myself to accurately track positions and things like eclipses, etc.

    Eventually I settled for using a program Greason Wolfe pointed me to: Here

    After playing with this for awhile I got a number of moons that were fairly stable for several hundred years. (Slight wobble to their orbits.) I did this by using mostly light mass moons, the dense/heavy ones were stuck about the middle near where our actual moon is.

    So, after I had that working, I just cheated. I calculated the period of each moon alone around the planet. Then I wrote a little python script to calculate the positions of the moons around the planets at a given time. I only want to use the world for maybe a few hundred years, and these numbers come out as close enough.
