The backbone has stations with EIXXXX in the source, and they do get  
mixed up with real EI aprs traffic, but only on the APRS-IS.  
Generally there positions wouldn't be in EI, and we don't gate them  
to RF, so it's not a problem.

Solution to what?  I don't see a problem. If the agency I'm dealing  
with/showing maps to calls it an ICP, and I call it an ICP, I put it  
on the map as ICP, why would I put it up as "0ICP"?. That makes no  
sense at all?
