Host B can do a string_to_object with a IOR generated by Impl A. How B
gets the IOR is up to you.

If I understand you correctly. Your clients can get a reference to a
gate keeper (point of entry which you buid) and let the gate keeper
decide where your invocation will go.  Another way is to use
interceptors and catch an invocation and have all your impls knowing
about each other so that they can distibute the load.
