[aprssig] Open Source/Commercial Use acceptable APRS Alternative?

Kenwood support was always a big issue with any changes. Another big 
philosophical debate (the one that had Bob and I blowing  up the SIG for 
a week straight and getting nothing productive done at our respective 
government jobs) was over who got to decide what types of traffic were 
permissible on network infrastructure and whose responsibility it was to 
ensure (for example) that proper PID parsing was used. I don't think the 
question was ever meaningfully resolved, but Bob and I were at least 
able to have a beer together and laugh about it at the next DCC.

I'd be happy to resurrect OpenTRAC if there's still a role for it to 
play, or to pass the torch to someone who wants to take the lead. There 
are things in there that I'd do differently now, and plenty of my 
original vision that was never realized, but it's not bad compared to a 
whole lot of legacy stuff we're stuck with. (I say as I'm taking a break 
from working on a /de novo/ EchoLink implementation and questioning my 
life choices.)
