Yes it has been theorized by several e.g. Shigeru Ida, Kenyon or Bromley (either or both) but in the Morbadelli paper, I think both Morbadelli and Levison have run their own simulations (see their paper) to show that such encounters (although they are sure to have occurred on many occasions...
Thanks Tony. :) I'm actually still waiting for Dr Paul Wiegert. For what it is worth, he and Dr Matt Holman once co-wrote a paper ( see Long-Term Stability of Planets in Binary Systems ) on the stability of planets in binary systems to get back to me. He promised me years ago to run some...
And guys, just in case you all get to think that this is nothing new but a rehash of Hut's/Muller's Nemesis Theory. I suggest you think again. There are a few things here that distinguishes the object that I am proposing here has an orbit nowhere bear that of Hut's/Muller's Nemesis.

GRAVITATIONAL POTENTIAL OF THE SUN AND WIDELY SEPARATED VLM COMPANIONS
We know that the potential of the Sun extends to Oort Cloud at least i.e. about 100000 AU and this is calculated from Newtonian gravity, except very close to the Sun where general relativistic effects may be significant for...

Dr Steinn Sigurðsson (Penn State) has been reporting findings announced at the Confererence on Extreme Solar Systems on his blog http://scienceblogs.com/catdynamics/2007/06/extreme_solar_systems_v_the_sa.php but amongst all the interesting discoveries is this idea raised by planetary dynamicist...
