I'm glad you asked.  =]  My chart is at http://n1vg.net/trackers.php.  Still
missing some inputs, though.

My own OpenTracker (http://n1vg.net/opentracker) would probably do it,
though you'd need to fudge the GPS/laptop connection a bit to share the
port - or at the very least, make sure the GPS is turned off when you're
programming the tracker.  The TinyTrak should be the same in that respect.
Both support SmartBeaconing.  Most of the time there's a distinct difference
in battery voltage when the alternator's running, and with the OpenTracker
you can switch profiles based on a voltage threshold, so that can be used to
switch beacon rates.
