Livetracking of GPSies.com
It should be a quick win ;-) because livetracking is already implemented into Pebble Bike. GPSies.com is (my) site and has tons of cycle tracks.
Livetracking is available for registered user. Every user needs for the tracking the username and a PIN (4 numbers, like a password). The PIN can be picked up here: http://www.gpsies.com/liveTracking.do (user must be logged in).
Here is the description to the livetracking:

Btw., I'm a fan of Pebble Bike and I'm using it every day ;-)
Thanks!
