Difference between wire tap and multicast

[Sylvester]

Hi,

Looking at the example on the website, it appears to me that there is no 
difference between a multi cast and a wire tap, except in the 
programmer's mind. Is this true? So,

  1. Is there a way of telling camel: "Hey this is a wire tap, not a
     multicast"? Or is the wire-tap just another endpoint that only the
     programmer knows is the wire tap and treats it accordingly?
  2. Is multi-cast the only way to implement a wire-tap? (both #1 and
     #2 maybe very similar)


Thanks,
Sylvester
