Precisely! That is what the APRS Status script does. It runs on the IRLP
node and generates an APRS object that contains the node number, the
frequency, offset, tone, and status. Oh yes... and the lat/long as well. The
object is sent to the APRS-IS.

No application is needed at the IGate. The local IGate operator just sets
the IGate to send the IRLP status out via RF. It would be sent once each
hour or when the node status changes. 100 km might be a bit outside the
aloha circle of most IGates. Probably a path of WIDE2-1 or WIDE2-2 might
be appropriate, but that is probably the default path of the IGate already.
