[aprssig] APRS resolution

[Scott Miller]

After the flamewar that the subject started here some time back, it's 
not something I even particularly want to debate right now.

As for how I expect it to be rolled out... well, I've got a decent 
number of commercial customers now, and quite a few amateurs operating 
in closed systems, so I plan to add OpenTRAC support to the Tracker2, 
including some things like crypto support (encryption for commercial 
apps, authentication for amateur) that add some value to the system. 
Beyond that... well, we'll cross that bridge when we get to it.  =]

That reminds me, I've still got to go recover the opentrac.org website 
from the old server...
