Yes

//    start the process to talk to
Process TrackersProcess = Process.Start(@"some good thing to starg",
TrackerBuilder.ToString());   

//  set me up to send
ClientChannel = new IpcClientChannel();
ChannelServices.RegisterChannel(ClientChannel, true);               
WellKnownClientTypeEntry remoteType = new
WellKnownClientTypeEntry(typeof(MTGClassLibrary.MTGTracksMessage),
TrackerURL);
RemotingConfiguration.RegisterWellKnownClientType(remoteType);
           
// here is the example

MessageTracker = (MTGTracksMessage) Activator.GetObject
(typeof(MTGClassLibrary.MTGTracksMessage), TrackerURL);   

If I comment out the start process the GetObject still works.
