[aprssig] IS-to-RF gating... A proposal

Here is an idea: use CQSRVR to send a CQ!  If someone on the local RF wants to hear who is nearby (and anyone else, for that matter, who uses the same CQ group), they send a CQ message to that group (you can have more than one group).  If anyone on the Internet wants to send out a CQ to that group, they can and that message will be sent to all group "subscribers".  This leaves it in the hands of the local RF users to determine if they want to see those people; it eliminates rapid-fire abuse as CQ server won't forward rapid-fire CQs.

Of course, it requires that the app user understand how to send a message and it requires an RF user  who wants to see those app users.  Hmm, local control, no software modification, no potential for rapid-fire abuse (yes, you can abuse the system still, but at least not by rapid-firing to RF from the Internet), no attempts to break existing servers, clients, etc.  And if someone actually wants to communicate with each other, they can (and by the way, associated posits will be gated).
