Making things movable is super easy with boost.move and it would be very
useful  feature imho. Using swap() for moving is preferred way to implement
move ctor/assignement anyway no matter how rvalues are implemented
(if it is actual support or emulation mode).

I now keep noncopyable objects in boost::container::vector and those
objects have
signal members which have to be kept with shared_ptr<> only to be able
to transfer
ownership.

OK, will try to do that.
