I saw an article about IETF work on geolocation and presence info linked off O’Reilly. This is very cool, I hadn’t heard anything about the GEOPRIV working group before, and it could mean that work in general on the subject is a lot further along than I expected it to be. However, work on standards is not a working project. There’s still a lot to be done in terms of making a working system, such as getting a good working set of maps. This should prove a very interesting additional point of entry into the subject if nothing else.
