Very nice, as usual!

Thanks, as usual! :)

Is there a minimum number of birds for lock? Is this checked and reported?

Minimum is have signal and locked to at least three birds for proper triangulation (at least with this unit). Even at three, I sometimes get sporadic values (very low values mind you) for speed and climb, even if I'm still. As soon as I'm locked onto four or more with this particular GPS unit, everything stabilizes and as I said, it's accurate across the board, from location (pinpoints my front door), elevation (I'm acutely aware of elevation in my area, plus I have other equipment that lines up perfectly.

Aside: Check out the Amateur Packet Reporting System(APRS).

Looks very interesting at a cursory look. Will definitely read more when I get home!

ps. I just did a sweeping update today to add further features... metric/imperial for measurements, signed/unsigned option for lat/lon (ie. -114.xxxxxx to 114.xxxxxW), full testing without needing gpsd installed, direction() to convert the decimal heading into direction (NNE, SW etc), and updates to the docs. (v0.02, should be indexed shortly).
