Wi-Fi Direct will connect at existing Wi-Fi speeds– up to 250 mbps. Wi-Fi Direct devices will also be able to broadcast their availability and seek out other Wi-Fi Direct devices.
Some of you might have heard me witter on about widely distributed databases (e.g. bit torrent) and mesh networks (e.g. OLPC). I made a few comments here: http://my-world.typepad.com/rworld/2007/10/more-on-the-mes.html
This post suggests that developments facilitating such a network are continuing. Yes, it may be a long way off but eventually there will be no telcos as we know them: no ISPs. We need to be thinking past the centralised data centres to the far edge: you and me and our various devices. Security will be a big problem: identity, access, spam and fraud. Curation will be a problem. But, if we don’t get washed away in a big glacial melt down (http://www.opendemocracy.net/article/the-coming-of-a-new-climate), one day there will be one big network.
