And even worse, not every packet (at least here in the US) needs to have
that ID. If you beacon a comment or a status report at least once every
10 minutes, you're legal (on the air), so any soft of filtering (that's
the bush we're all beating around, right?) would have to be stateful and
remember which stations had a "legal" identification within the past "N"
minutes where "legal" and "N" are locale-specific and therefore nigh on
impossible to do on the APRS-IS backbone IMHO.

PS. Now, to figure out how to implement locale-specific filters to
mitigate the risk to bi-directional IGate operators for third-party
message transmissions and/or APRS-IS to RF IGate rules... Especially
when the first packet that said IGate might see is a message from a
distant source destined for a recently local station... And even worse,
when the message sender is using a tactical station ID and relying on
comments or status reports to provide legal identification...
