title: Multiple consumers for a single queue in MassTransit
body: <p>Is it possible to have several consumers listening on a single MSMQ instance and use the Selective Consumer interface for having each one deal with a distinct subset of the messages?  I can't seem to get this scenario to work correctly using pub/sub - a single consumer on the queue works fine, but when using >1 consumers (several instances of the same executable) no messages appear anywhere.  As I understand it, this is not the case of 'competing consumers', since only a single consumer will process a single message.</p>
  
  <p>Any help or pointers are appreciated.</p>
