Many people are working on this, including ourselves. From our
perspective, we're working on a way to publish this information for
exactly this purpose, in a common and open way. blah blah, something about
distributed geographic spatial-data repositories in a multimodal way with
p2p technologies blah. We've been working on a client, too, but we need
some help.
There are a few commercial vendors who are trying to market this
to corporations. I don't find that this technology would be useful in the
office, unless I were looking for chow foon durring lunch, tho.
Check out Placelab, http://www.placelab.org, they have a bit more
information.
