Hello everyone, I had a brief look at GEOPRIV and I was very much impressed, There has been so much work done by this amazing group!
At the same time, I would like to raise my concern regarding the http location request which will not be detected by layer-3 devices (Routers), I am anticipating that in the future, GPS capability will be added to the router itself (just like smart phones) and packet marking and classification based on geo-location will be required. QoS, firewall and routing based on geo-location will be highly demanded when mobile routers move from one geo-location to another which has different regulations/electronic laws. Here is an example, if your router is within city-X and this city has very good electronic and copyright laws, then users will have relaxed network security settings, but what if the very same router moved to city-Y which according to its law, certain websites should be blocked (like facebook in china for example) .. these rules based on geographic location won't be feasible unless the mobile router has a GPS and can read/write coordinates to layer-3 packets.

Sounds awesom, but in this case all webpages, phone applications, server side scripting languages ... etc have to be modified to support the new application protocol. Not mensioning that layer 3 devices (like routers) won't be able to support the feature, let's say in the feature you want to do dynamic routing based on geo location. In anycase, I still feel quite interested about the new layer 7 protocol, will try to go through the GEOPRIV documentation this weekend in order to get more details.

I agree with you that IP addresses are not very reliable as a means of determining geographic location. That said, I don't think it is a good idea to add GPS position to every IPv6 header. It would add a lot of overhead, there are many privacy related issues (as others have pointed out), it doesn't need to be in every packet. An alternative would be to create a application layer protocols that could request and send GPS positions. That is a better way to to deal with the privacy issues and the GPS position would only need to be sent when desired or when requested. The GEOPRIV working group is doing some work in this area.
