There is no single point where such a collection could be made, the  
dup filtering happens at every stage. Such a collection would require  
every IGate have two connections, one to the current APRS-IS, and the  
other to this new collection point. Furthermore, the findU-like  
database better run some SERIOUS hardware, the write load on the  
database would be many times greater. In other words, it is simply  
not practical.
