To move trace data from client to server, the RPC call must be annotated to take a TInfo object
as its first argument. The user can simply pass null, so long as they wrap their Client and
Service objects with these functions.
Trace.on("remoteMethod");
Iface c = new Client();
c = TraceWrap.client(c);
c.remoteMethod(null, arg2, arg3);
Trace.off();
The wrapper will see the annotated method and send or re-establish the trace information.
Note that the result of these calls is a Proxy object that conforms to the basic interfaces, but
is not your concrete instance.
