The socket-can stuff is mature enouth to have been used in some projects at Pengutronix. In december, we have made a synchronisation meeting with the VW people who made the initial port for 2.4; they are more focussed on having higher level transport protocols ontop of the "raw" socket interface we currently use. During that process we have reviewed the user interface with regard to their use cases, so it will have to be changed a little bit before we have something which is in a state to be posted on lkml. Unfortunately we have no commercial project behind the infrastructure work, so it's priority is lower than it should be to really drive things forward (paying customers have a higher priority than community work).
