Hi, Steve.

I agree with some of your statements, but I have some questions about others.

Actually, aren't there 3rd-party traffic rules, such that, for example, Internet traffic from certain countries can't be transmitted by a US ham (because the US doesn't have an agreement with that country to allow 3rd-party traffic)?

Agreed.

Unless that non-ham is prohibited from being a third-party for whatever reason.

Uh, how _can_ and _do_ we handle it at the present time? Do we have blacklisting
ability in every I-gate to block an offender? That's asking a lot of the thousands of
Tx-IGate operators, who probably aren't monitoring every single station gating to
RF through them. The problem still exists (in a smaller scale) in the APRS-IS
servers, because it only takes one party not enforcing the blockade to let
offenders through.

Frankly, I don't think this whole thread would have gotten started if it weren't for the problem that we _don't_ have a way to handle it. APRS-IS doesn't have the central
authority and resources to automatically and selectively censor traffic.

I tend to concur with your legal assumption; I was merely stating technical issues
in my previous email.
