Well, the "trace" shows the packet entered the APRS IS at  
first.aprs.net. None of the APRS IS hub programs keep logs that even  
keep track of where people were logged on at a given time, much less  
where each packet came from. So yes, if your idea of a trace is to  
first, then you are right. I use trace to mean to identify who, or at  
least an IP, a message comes from. And you are right that even this is  
not reliable.

I'm able to tell the IP of any message sent through findU's message  
page as long as someone asks within a week or two. Very few packets on  
the APRS IS can be traced that specifically.

Which word, deprecated? In case you or others are unfamiliar, that is  
in common use in computer science for something which is supported  
now, but not recommended and not guaranteed to work in the future.
