Hmmmm.... XMPP??? As in jabber? It's the a Wetnet opportunity to play in
I'll have to keep my eyes open for APRSDroid V4.1.

I fully support the new X-APRS protocol initiative, it just plain makes
Experimental services are already live on aprs.fi, with IPv6 and load
balancing. "telnet xaprs.aprs.fi 20482" to see the convenient, easy-to
parse and lightweight data stream.
I've also set up a service on the AMPRnet/Hamnet: telnet 184.108.40.206 20482
With a little effort, I'm hoping we could phase out and turn off the
legacy APRS-IS services by the end of this year.
