Not really. If I send an object to RF, it will enter the APRS-IS from
another source. IGates.

We also saw how Firenet could be abused. Someone could easily take those
objects and flood them to RF. Once that happened they WOULD appear on the
APRS-IS, because they re-entered the APRS-IS from IGates that heard them
on RF.

This is not to currently criticise the folks at Firenet. When they first started
the 'Sea of Blue', they experimented with the APRS-IS in the art of mass flooding.
There is nothing in place that prevents an 'object' from entering the APRS-IS if it
is sent to RF.

The truth of the matter is that Firenet objects are seen on the APRS-IS. I think
we can expect to see more of this happening... ECHOLINKs, WINLinks, etc. are good

Firenet opened a whole new thinking process to experimenters. One thing that would
help prevent flooding to RF and back into the APRS-IS, would be TCPXX.

The APRS-IS is unmanaged, therefore we all have opinions on what's acceptable.
Everything has to start somewhere... how do we know it doesn't belong on the APRS-IS?
The Firenet Group was a great example of yielding to persuasion, and adapting to
some basic common sense. I could be wrong, but I don't think Firenet is a popular
concept. The Firenet client base hasn't changed much from it's inception. What's popular,
if anyone else has noticed is what Bob Bruninga commonly refers to as 'human intervention'. That 'would' include messaging, but not some automated process that promotes mass
injections, that swamps our average internet connections.
