How would planets orbit in a binary star system?

How would a solar system of planets work around a binary star system.  Would keplers law  still be effective since there is another focal point?

Such systems have been observed, I don't know how stable they are.

For planets at a great distance compared with the binary pair separation, the orbit would probably be much the same - i.e. stable. For close-in orbits- God knows- probably pretty unstable.

Don't I remember that Dave Shorts knocked up a graphical representation of this? One where you could place the objects where you wanted to see how they would interact?

DAAAAAVE! Where is it?  ???

That is most interesting; it shows that such systems are possible.

For some nice animations of binary planet systems.

Wah!  the first link doesn't show me any pictures and the second link produces a 404 here :(
