I have published iGoogle widgets with similar functionality for 12
different transit agencies (
http://bit.ly/FAfCz ) using the API that
I announced a while ago (
http://developer.thenexttrain.com/) but until
I have gtfs data for metro north, I can't do the same for them. If
anyone has an access to an official or unoffical gtfs file for metro
north pass it along and I'll get a widget up almost instantly.
(only 9 of those widgets show in the iGoogle directory, you can find
links to the rest via http://thenexttrain.com/ at the bottom of any
schedule)
You should also be able to use my json api to write a matching
yahoo/apple dashboard widget.
