Digging around on the Nokia site I found info on Nokia Sensors. Using Bluetooth you can connect Peer-2-Peer for Social Networking and File Sharing.
Nokia has created a great microsite that has a demo, free download of the software and FAQ's to outline how to use the saoftware.
Some of this stuff is great in that it can enable users to link and communicate without the use of a Mobile Network so perhaps the next time I am on the tube with friends we can keep "chatting" whilst travelling or when in a conference that has no network coverage.
My only concern is the Free File sharing side of the service could be something that limits Nokia's development of DRM technology and the uptake on new content.
