I'm not sure if I'm mis-understanding you here. Yes, the IGate operator must
intentionally gate the object (because he wanted to or because the IRLP node
operator asked him to) but once the IGate operator has added the object name
to his IGate settings, he doesn't have to touch it again. For the object to
exist, the IRLP node operator must install the APRS status script.
IRLP Node operators can see aprs_status-4.0.tgz at
http://irlp.kc6hur.net/irlp_scripts.php to install the script on their node.

Did you find these?

Agree completely. But requiring 10,000 non-APRS sysops and owners of ILRP
and ECHOlink nodes to invest in a separate 144.39 TX and a TNC to generate
the object is never going to happen (though a few did).
When solved this by asking the IRLP and ECHOlink systems to simply generate
the objects onto the APRS-IS so that the objects at least existed from a
reliable source, and then they can piggyback on the existing TNC and
existing TX of the local Igate. Done...

To provide a local RF service, the Igate should not just be a
plug-and-forget. The SYSOP should be kept informed of the local RF domain
and the local IRLP and ECHOlink sysops should request that the local Igate
have these two local objects passed-to-rf.
I see these local resource sysops working and talking together so that the
APRS map display in each area does represent to the local community, what
the leaders in the local community feel are important RF assets.
The burden is not just on the Igate (though he has to make the entry to
activate the object). The other observers need to keep these sysops
informed of any major change in the local assets that would need to be
reflected in the Igate settings.
>This is true of Hospital, EOC, Police, Fire and other objects.
No, these are not RF assets, and they do not have changing STATUS that is
of immediate need to local RF operators. None of these objects are
initiated on the APRS-IS anyway. Anyone in the area that activates an EOC
or a Firestation forsome immediate event, is responsbile himself for
placing it on the map.
The only APRS-IS initiated objects to my knolwedge that fit the category of
needing to be added to the local Igate pass-to-RF list are the desired
local IRLP and ECHOlink nodes.
>I would not like to receive a call about all the objects I am gating to RF.
I agree completely. No one should be transmitting -routine-, inanimate,
non-RF objects to RF. I see far too much of that and it is a waste of
resources. Especailly, since built into APRS was the feature to QUERY for
EOC's, Query for hospitals, or anything else so that they couild be
tranmistted on demand, but no one wants to see these objects all the time.
But we are only asking for two local objects in the coverage area of any
given Igate. That is, the active IRLP and ECHOlink objects.
>It makes better sense for the local stations to generate the RF information.
Better sense, true, but will never happen. That's 10,000 TNC's and 10,000
radios someone has to buy and it simply wont happen.
I think we may be talking apples and oranges. Here are my key points:
1) No one likes to see routine objects of no immediate RF value
2) We are never going to get local IRLP and ECHO nodes to generate their
own
3) It is so simple to generate them in real time on the APRS-IS straight
from the IRLP and ECHO central database so that the object reflects the
real-time status of the node.
4) All we are expecting is for the Igate operator to be knowledgible of the
RF assets in his community and to assist the local are in putting these out
by adding them to his pass-to-RF list.
Hope that helps
Bob, WB4APR
