I think the suggestion is for RF stations to put ISONLY in their path to 
prevent RF propagation (digipeating) by theoretically intelligent 
stations that "know" that the packet has been delivered to APRS-IS.

However, IMHO APRS is about Local knowledge and propagation and the 
APRS-IS is simply a nice way to provide global glimpses into that local 
information.  And this from the author of what started out as an 
APRS-IS-only client application....
