Lanes already solves that afaik, there is also [Eris](
https://github.com/fnuecke/eris) that can serialize just about anything. But neither of those have shared mutable state across threads. Well, that's not entirely tru because lindas in Lanes are shared, but they are just used for sending stuff between threads.
