In principle SSDV frames could be transmitted through APRS just as fine 
(imagine live pictures popping up at various places on the APRS map).
However we already have extremely high APRS packet collision rates at 
some regions and hot running aprs.is servers so that I hesitate to 
encourage it. The solution is probably to shift to higher frequencies 
and baud rates for this. I wonder if the aprs.is backbone could handle 
that. Maybe the backbone specialists could give us some idea what is
