we will (i just got access) use it as another hint on the RHS of things. I have not done enough 
research on the zone to know exactly where it fits in with things. I've always understood it is 
valuable to some registrars but havn't learned how it can be leveraged yet.

one thing that comes to mind is where are the codes to decode the responses?

ie what does 127.0.0.{3,4,5,6} mean?

on using the zone for blocking spam, i wouldn't.
