This is pretty much how Google+ is going to work. They're merging Latitude with it at the moment so you can share your location to the 'family' circle and see where people are. They've got google docs which has identity integration already etc.

They're not too far away really. G+ is their plan to do this.

Won't that require the person you're sharing with to be on G+? Currently I share with family who has no interest in that by embedding.

Google+ does support having email addresses in circles, but I don't know if Latitude will work with that, sorry.
