One thing we're looking to reduce/eliminate is the "Sea Of Blue effect
when folks start putting all CWOP data back out on RF. javAPRSSrvr has
modified over time to do that. CWOP non-hams are not validated
connections and thus shouldn't go out save when we're looking at
compelling need: emergencies like chemical release, severe weather, etc.
Using cwop.tamu.edu as an aggregator of all three CWOP servers allows
this.
A second instance of javaAPRSSrvr is pretty straightforward. That'd be
my recommendation but pose this to Pete on the javAPRSSrvr list and see
what he recommends.

ok, feeling dumber yet answering my own question.
Is the logical answer to deploy a second instance of the APRS server SW
here, take the firehose from CWOP's servers, then allow the internal
clients to filter it to the region of interest? Running it on linux, a
second instance running on the same box shouldn't be an issue should it?
You can definitely tell the CWOP feed on the Xastir status line. It's
the one with the red arrow lit all the time :) Sure makes the station
names zing by also on the status line.

Here's sort of a (dumb) question:
I use javaAPRSSrvr locally to aggregate all my APRS traffic from a
144.390 digi, a weather digi and two Telpac's for Winlink, as well as
Xastir. This server then establishes ONE bidirectional connection to
the *.aprs.net servers. If I wanted to bring in a feed from the CWOP
servers, how do I configure a readonly simultaneous upstream to go
along with the aprs ones? Basically, I want to aggregate it in the
local instance, so I can filter, db it, etc, but NOT gate CWOP servers
back to APRS-IS?
Thoughts?

At a minimum a CW station should be required to be wx and the last
four characters should be numeric I would think.
Correct. I'd also recommend that we look explicitly for APnnn,
ARnnn, ASnnn and that we consider making this a user-configurable
area that gets updated periodically by developers or maintainers to
be "the default list"
*TOPIC 2*
Please consider connecting to cwop.tamu.eduport 30001 for gathering
your CWOP data. That provides a full (nope, no filters) feed for all
CWOP data including APRS-Wx (ham: not CW/DW) stations.
There are 3 CWOP-dedicated servers. These are for the CW/DW
stations. Hams should continue to use the APRS-IS servers _unless_
you don't want your data pointed to RF.
Questions will be entertained. We're trying to get CWOP covered with
its own servers to improve CWOP *and* APRS performance.

So no, it won't recognized DW's. Yet.
