How is that abusing Firenet?  Seems that an errant Igate would be
abusing APRS-IS in that case.  Go after the igate operator, or the
author of the igate software who coded it wrong (yes, I'm well aware
that could be me in the future, but if I make mistakes like that, I
try to correct them).

Actually, there was no "firenet" as such until after the "sea of
blue" discussion, where people didn't want to see all the weather
objects.  We've been very happy "flooding" our Firenet servers with
10,000 to 15,000 objects of all types, having to do with weather and
lots of other useful public service type objects.

You're funny!  What I recall is that echolink/winlink objects were
posted by someone else, not firenet folk, to the aprs-is, and posted
directly to aprs-is.  Don't confuse firenet stuff with that.  Yea,
we were posting our objects to Firenet as well, but you're confusing
two different folks here.  There were two people generating them.
Firenet had nothing to do with the APRS-IS objects you were seeing.

And all igate software uses that as far as I know.  Xastir does.  It
skips gating RF->INET if TCPIP/TCPXX/RFONLY/NOGATE are seen in a
packet.

I don't recall EVER seeing any comments among the Firenet guys on
the firenet mailing list as to whether or not what we were doing was
popular.  It's not the point dude!  It's a public service.  It
doesn't need to be popular to be successful.  I don't do SAR or
donate money to my local church to be popular either.  It's not the
point.

Great!  I'm one of them.  Both a user and one of the massive object
generators.  Perl is wonderful for that.

I see you're carrying some excess baggage into the discussion here,
which really has no business getting brought in.

Firenet guys are happy over there playing in their own sandbox, why
aren't you?

If you don't want your internet connection swamped, don't connect
to Firenet.  Problem solved!  An alternative is to connect to a
filtered feed (port 14580) and just snag the type of objects you
want.
