[aprssig] Newbie APRS object question

[Lynn W. Deffenbaugh (Mr)]

I will go on record as saying it's probably "bad" to have an IGate gate 
objects from the Internet to RF.  I would have serious trouble figuring 
out just which objects to gate and as AI4PX pointed out, the pathing 
and/or actual broadcast location might be centered on the object's 
applicable area.

Remember, object IDs are not necessarily unique and anything coming from 
APRS-IS can be spoofed, so even gating "objects owned by/originating 
from" a specified callsign can have unexpected results.

Lynn (D) - KJ4ERJ - Finally clear on where you are and what you're 
attempting!
