[aprssig] APRS Email (better way)?

Oh yeah, I had a "duh" moment just as I hit send.  Since APRS messages 
don't contain any position information, in order to do any of the fancy 
stuff, the e-mail servers would need to buffer the most recent position 
for every station on the planet just in case they send an e-mail through 
the server.  Either that, or they'd have to hold off the e-mail hoping 
that a posit comes through to complete the information in the body.

Sites like aprs.fi make it easy to forget that they represent a 
composite, time-accumulated view of APRS backed by a full planetary feed 
and a database of APRS-supplied information for every station.  Like I 
suggested below, a simple, robust, single-function e-mail server would 
be my preference.  If someone wants more data, they can click a link or 
access the information elsewhere.
