Feature: Remotely affect actors and perform configuration

[n8allan]

The proxy builder in this framework would make it very easy to have a "remoting" (RPC like) representation of an actor that is out of process. It would be nice to take advantage of this to enable coordinated networked actors across processes. At a minimum this would be useful for remote administration, but could also enable networked topology for distributed machine control, or serve many other general purposes.
