We wish to use ST_LOCAL for this, yes. ST_VIATNC is the other flag
bit I was referring to.
Right now, the decoding doesn't take into account the wide-area
digi's and how they do or don't affect the '*' in the header. We
need to fix that.

Yea.

Yep.

Yea, but I think we'd want a much longer expire on them, that's why
I suggested the delete-from-database time, except it would be
checking the "last-heard-direct" timer, and if too old, resetting
the ST_LOCAL bit for that station.
