Both is communicating, even if the message of the latter is only
"here I am [and you can contact me on this QRG]".

Thus I suggested implementing a new protocol _and_ a proxy software to
allow old applications to be used in a secure way. Please read up :)

At least we seem to agree on the fact that APRS-IS as it is now can be
improved upon.

Of course an igate operator has to decide how much traffic he is going
to allow to pass from IS to RF. It is his direct responsibility after

I am designing my application with the idea in mind that anything it
generates will land on RF. Except from a bug (which initiated this
lengthy discussion) I have not seen evidence for misbehaviour or even
abuse. Why should people start abusing APRS-IS just because somebody is
forwarding their packets to RF?

I also suggested using separate limits for messages and other packet
types per callsign, thus preventing the issue you outlined.

Of course it is clear to me that reverse iGating is complicated.

outlines all the little and big problems already. My point is to have a
discussion resulting in either a software which is easy to configure or
at least sensible guidelines to make life for iGate ops easier.
