[aprssig] AX25 Protocol group (Jack Chomley

It'll only affect AX.25 applications if anyone elects to use the new 
protocol.  If the extension is not being done in a manner that's 
backwards-compatible... well, good luck with that!  It's not like 
someone can throw a switch and turn off AX.25 2.2, and unless there's a 
compelling reason to switch for a large portion of the user population, 
no one's going to bother.

Is the working group even a going concern these days?  Or has it been 
reconstituted?  Last time I tried to get a PID assigned NO ONE seemed to 
be answering the mail there.
