Wow, why not write a simple background APRS application called
APRS-XO that only has to do one thing.  That is, to report the
XO's position to the APRS-IS when ever it is in range of
wireless access to the internet.!  See my proposal:

It does not need the other 99% of APRS (maps etc) since a simple
URL to one of the APRS MAP web pages could plot then all the
positions of all other other XO laptops!  Done. 

Just like the APRS-IS now can handle both licensed and
unlicensed operators, those XO owners with a call, will be fully
APRS functional, and those without the APRS-Validation will
still show to all other XO laptops but will not appear back to
RF.  That mechanism already exists and works!  Done!

Then the XO's can display all the other XO's in their area, AND
can APRS message or anything else that APRS can do!  Normal HAM
operators can use them fully on APRS...

Can someone propose this to the XASTIR LINUX group and see if
someone wants to write this?  This is not a mineature xastir, it
is simply a script to do these three things:
0) Accesses the APRS-IS when on line...
1) Sends out a posit once every 10 minutes
2) Receives any incoming APRS messages
3) Can send an APRS message 
4) Has a URL to a dedicated XO page on an APRS-IS web page...

What am I missing? Is this trivial or what?
