I've come across the same problem some time ago,
so I implemented a macro which calculated an
electrostatic-repulsion algorithm. Some animations of
this macro can be found on my website.

If you want the code, I can see if I have to clean
the code a little or if I can send it to you right
away, just give me an email-adress.

Regards,
Tim
