You have probably a similar discussion...

For a SGATE we are not discussing RF performance analyzis etc but the  
possibility for users to use i.e ISS to post a position via RF trough  

Using APRX as an IGATE is now posting "false positions" for a user as  
it insert them even if it was not digipeated by ISS.

This is misleading as users then seems to have been using a satellite  
but the real story is that the local igate just inserted it.

So for regular terrestrial APRS use i agree that this is not something  
APRX should do differently. But for satellites it's a bit different as  
"direct" positions are a false position and has gone directly to an  
IGATE and not via "space".
