CCP seem to have confirmed Walking In Stations is now dead in the water with no rescue and resuscitation likely in the foreseeable future.
Here and here.
While it's a shame, the reasons are sound however it will make gathering new players more difficult if "internet spaceships" are not their primary interest.
I wouldn't expect this feature to be available for at least two years, four years wouldn't surprise me either.
So don't hold your breath.
