LongLatMe: Location-embedded SMS

So, let’s say you want to meet up with your friends.  You text – “Where are you?”.  “We’re at the Bar Bar on 59th Street”, they reply.  Now you need to look the place up, and navigate your way there.

Instead, why can’t your friend just send you a location object within the SMS, encoding their current coordinates.  The ability to locate exists, all that needs to be developed is a generic method for integration with all current mapping applications, allowing you to easily route your way to their location.

Does this exist?  And, if it doesn’t, then why not?  I’d be amazed if Google haven’t thought to implement this with Android.

Edit: This exists (well, of course it does!) though with not as good a name.  You can find out about ‘GeoSMS’ at this wikipedia page…
