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 [:(]
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
