Sounds great - now if Apple and Google would get together and enabled iPhone/iTouch for it, and there was ubiquitous wifi in urban areas, then we'd be much safer walking the streets.

It all bodes well for the handheld, but maybe not for pedestrians looking where they are going rather than at their handheld ;) - Jo Booth via FriendFeed MT Plugin
