You may be aware of Google Latitude which provides your location to a limited set of contacts, which is great for keeping in touch with Friends and Family.  However, what do you do when you want to share your location temporarily with Customers or Coworkers?  Glympse solves that problem, at least for G1 Owners anyway.  Glympse is a great tool to add to your business arsenal if you are in a customer oriented business or even on a limited basis for other lifestyle actions.  Basically, with Glympse, you provide your location to a recipient of your choosing on a limited basis.  Going to meet a client for lunch?  Send him a glympse when you're on your way.  From his desktop (if he's meeting you at his place) or his G1 (should he have one), he can see how far away you are and know when to expect you.   He, or she, can watch your location on your route.  Sure, this can be done with Latitude, but what this does is allow you to temporarily add a person, set it for an hour (or the time of your choosing) and during that time they can monitor your location via the link your device sends out. Afterward, the 'location' expires and they can no longer track your position unless you send them another invite.   This is a great tool for arranging meetings with people, they can come down to meet you when you're close without you having to text or call (while driving).  Visit glympse.com for some other great uses.  They also suggest using it for your family so they can know when you're on your way home.  I'm not so sure about that use, I still think you'd use something like latitude for that, or maybe an 'always on' location system. I for one wouldn't want to have to send my location home every day.  But, maybe that's just me.  According to the site, they're making apps for the iPhone as well as the Blackberry, which should increase it's business functionality.
