What do you mean by blocking?  The receive call will block until a message matching one of the supplied types arrives, but if you don't like this you can always use receiveTimeout.  send() doesn't deep copy objects, so the only reference types send() will currently accept are those labeled as shared or immutable (Unique!T will probably be added at some point, which is more appropriate for your situation).  So to use send() known unique reference data you'll have to cast to/from shared or immutable.  Nasty, but it'll work.
