This is not an appropriate solution. When a distant ham sends a  
message to a local ham, the IGate sends the message along with the  
most recent position of the distant ham. These packets MUST be digied  
to the local area, even though they did not originate locally.

There are many other examples, e.g. weather warnings, that do not  
originate locally but which should be digipeated. You are suggesting  
using a nuclear bomb to kill an ant! The solution is far worse than  
the problem...
