Hi Stuart, It is my understanding that all of the difficulties come from proxing concrete classes, not interfaces (the latter can be proxied quite easily using the core API). I think it's well worth using two different implementations for interfaces and concrete classes so long as the differences can be abstracted away from end-users and it really overcomes all the limitations I and you listed (i.e. EJB containers).
Let's ask Johan, perhaps he's already investigated EJB space.
