I think (approx) 1 will "get through" and all subsequent ones be 
considered dupes and dropped, at no great load to the APRS-IS backbone. 
This will unfortunately mean you won't be able to get a particularly 
good picture of who's receiving it, as only one "igate" will "get in the 
log". You might see slightly different views of "who got in first" 
depending on where you sit on the APRS-IS network, but certainly won't 
get a big picture or be able to publish "longest path records" or 
anything, at least not that way...
