glympse goes live on Android
Glympse is a service that lets you share your location for a specified amount of time from an instant, to 2 minutes, or to a few hours. It really is a good alternative to those short phone conversations updating multiple people where you are and even easier than texting. What you do with glympse is either “send” or “receive” one.

Glympse is a service that lets you share your location for a specified amount of time from an instant, to 2 minutes, or to a few hours. It really is a good alternative to those short phone conversations updating multiple people where you are and even easier than texting. What you do with glympse is either “send” or “receive” one. The good part is the receiver never has to install any applications - they just need to click on a URL sent out by the service. Being constantly watched is a scary idea but the timer function of glympse should give you a bit of a peace of mind knowing any glympse you sent will eventually expire.
Currently it only works on Android - mainly T-Mobile’s G1.
The video is pretty good:
