- Add an interface to the data from the gps command.
- FAP calculator.
- gpsd integration so D2 GPS can be used by gpsd.
- sample cron jobs for running dsumap at least once per 10 days.
- debian.org LDAP position updater?
- Add support for async reads of values -- ask an object to start
  retreiving a value, and then poll it until the value becomes available.
  This will allow for updating values as often as possible while doing
  other things, and allow for this next item..
- add position info to satctl move interface
	(without slowing down updates too much; but still need to query for
	position info because moves may be interrupted, so just doing math
	ourselves won't work)
- avoid multiple keypresses getting stacked up in move interface
