Attachment isn't found on the server, can I grab it out of AFS somewhere?

Does the empeg tick it's clock in local time or UNIX time? I guess that if we want to send some initial coordinates they would probably come out of config.ini, so we could store a timezone offset in there as well.

ETE is continually changing. Initially I just did total distance / gps speed, which wasn't working too well, so then I tried averaged speed, then velocity made good towards the closest point in the route, still no good. Now it is averaged velocity made good towards the next waypoint, which seems to be giving the best estimate up until now.

That tripmate initialization sounds like a trivial addition to the NMEA parser.
