[aprssig] Throttleing EchoLink Objects

I agree the load is an issue.  However, where I would really like this 
info is on my d710 for auto tune.  When I travel the US I have had many 
instances where I don't know the local EchoLink node and so badly want 
to check into one of my nets from another state.  I have drive to find 
Internet terminals if I can't get it on my iPhone just to find the 
nodes.  I have also done the drive and type on the phone to find them 

I liked the idea of being able to know if the node was free, in-use, 
offline, etc....

I do agree this probably should be handled at the local IGATE level.  
However, without the data from the XML parse I can only put out a 
non-informative object for my nodes.  I really like the IRLP script that 
puts out the status, although that has had formatting issues with the 
d710 also that are being worked on. 

There is no way I can see a 10% increase on the APRS-IS as worth it for 
those of us grabbing the full feed still, but if there was a single 
separate server with the data and each IGATE operator (if so desired) 
can connect to there also and grab the live data for his local area with 
a simple filter and put it out with a local path it makes some sense.  
Additionally, if that single server was able to be queried (ie. CQSRV) 
and that returned to the APRS-IS and any IGATE the local object one time 
only I think you have the best of all worlds.

I'm just saying I see both sides.  I love my cellphone and the Internet 
on it, but I also like my d710 and the TUNE button...
