This is pretty much how EchoIRLP does it, and something I remember 
suggesting way back.

A more "correct" way of doing it would be to flag your node as busy, 
which is achieved simply by putting your _own_ IRLP node number into 
$LOCAL/active.  When other IRLP nodes attempt to connect, they see 
you as busy, and the status page will report you as "connected to 
Echolink", instead of "offline".  This is the method EchoIRLP uses, 
which was worked out in consultation with Dave Cameron many years ago.

I think if the above is implemented, and run past Dave Cameron, you 
have every chance of getting AllStar back into the IRLP fold.  This 
is all that was required in the first place.  From what I understand, 
and asking questions of the Asterisk gurus, this is entirely 
feasible.  I just never had an AllStar node working to develop it 
myself (and that can't happen until later this year at the 
earliest).  I have the hardware (a couple of URIs, radios, etc) and 
the AllStar node number, but am in a somewhat temporary situation at 
the moment.
