Yesterday half the ISS crew returned home. Russia says they've fixed their problem so the next crew should go up Nov. 14th, but if not the ISS will be vacated Nov. 22nd.
SpaceX needs crew on board to do their demo resupply mission. Ironically, they could also deliver crew (w/o a launch escape system for now.)
Once there they become a more capable lifeboat that could remain on station longer and bring back more astronauts at a time adding to the safety of being on the station.
But they don't get paid until NASA gets it's act together. I bet they negotiate a better contract next time. Having more than one destination would be a good idea as well.
