This sort of reminds me of an old agent based Java middleware called Voyager I've encountered sometime in the 90s. The rough idea of this middleware was that you could write Java class derived from a special prototype and the instance of said class can travel around various Voyager servers all over the world to perform tasks on local context and then come back with the answer. Could be used for the whole bunch of scenarios from map reduce to accessing some content that only available at particular place and not accessible by public API. It was neat. Not sure what did happen to this middleware later on.
