Using the International Space Station as a starting point for a lunar flyby mission

Take a look at this BBC article on an idea that is floating around now for a mission that would begin at the ISS with the assembly of a ship, which would then carry out a lunar flyby and then return to Earth. It's a great idea and one of the best ways to make the presence of the ISS a meaningful one, now that it is almost finished construction and will be funded until at least 2020. The mission is quite easy in comparison with a lot of other proposed missions such as a manned mission to an asteroid, would be the greatest distance we have been from the Earth since the early 1970s, and being an international mission it would be a first for every participating country other than the US.
