another GPS idea - speed-sensitive voicemail

[Mark Eichin]

Use case:

  When I'm walking around, I'll answer the phone.  When I'm driving, I
  won't (one phonecall == two beers worth of distraction)... but am
  willing to pull over if the caller thinks it's important enough.

  I shouldn't have to *tell* the phone what mode I'm in: GPS can
  provide velocity information.  If my speed is over 10mph, the phone
  should pick up, dump a pre-recorded explanation to the caller, and
  let them "press 1 to interrupt the driver, or just wait a few
  seconds and leave voicemail."

http://wiki.openmoko.org/wiki/Neo1973_Audio_Subsystem implies that
call recording is possible, so the audio paths are there, right?  If
so, a lot of local voice-robot stuff is possible...

(And if your thought is "what if I'm a passenger" - the answer is
"this feature is not for you, it's for me" :-)  (Also, if you're not
an American, this feature probably isn't for you either :-) :-)
