ideas pertaining to the multiverse (in the Snow Crash sense) and augmented reality:
- neon outlining -- so you're walking down the street (in reality) and you turn on your augmented reality overlay in your glasses/contacts/cortical interface. Now other people appear, presumably appearing with indistinguishably real rendering quality (this is the future after all). But we need a way to distinguish them from real objects. So, outline their borders with a neon color. In addition, some people might simultaneously have their avatar in some online world be in the corresponding place as their real physical body is -- one might say that, unlike some people who are virtually there but not physically, and some who are physically there but not virtually, these people are simultaneously walking down the real street and walking down the virtual street. They get a neon outline too, perhaps a different color or thicker (or thinner) or more transparent or something.
- the objects in augmented reality can be placed in the same "multiverse" framework as pure VR locations such as OpenSim? and Second Life. That is, the real world can be addressed as if it were just one world among many in the multiverse, and coordinates to a location in the real world can be given in this fashion. This also implies that multiverse systems like OpenSim? should support the same geocoordinate systems used in specifying locations in the real world, at least as a special case.
- an idea complementary to the multiverse would be a relative DNS/URL/addressing system -- that is, rather than have a single global authority assign a name to each multiverse, each VR universe has its own URL/DNS system that lists the names of other known VR universes. A user by default queries the URL/DNS of the universe that they are currently in, but they can also establish a 'home' universe that is always used for relative URL/DNS lookups, and just like the 'hosts' file in GNU/Linux, they can also have personal names for certain universes that the take with them.
