And this is what we want and it solves a lot of problems without making 
a second APRS-IS network, special scripting etc.

I have not been exploring the source code of APRSC yet. But adding a 
flag for sgate mode and include the 15sec delay should not be that much 
work? If we are affraid that people are using the function wrong then 
make it "difficult" to enable APRSC in SAT-mode.

People expect to use i.e aprs.fi so a second aprs-is network is really 
not a good option.
