    RudeDude asks: " While reading Cryptonomicon I became a bit paranoid about encryption and digital signatures but it has me thinking a bit as well. I'm trying to visualize a way to prove my physical location in a cryptographically strong way and I can't think of one. My digital signature proves who I am, but wouldn't it be nice if I could also give proof of my physical location at a given time stamp? I've thought of only a few things that would be very hardware dependent, etc. but what I really think would be cool would be something that is as strong as digital signatures. Some sort of GPS/MD5 signature that a third party could confirm so that it would be impossible to spoof my location. " This question has been asked a bit by people looking to restrict services to various countries, but currently one can't be sure if the IP a person is using is really the location from which the connection is being made. Would a system like the one described above be a possible answer?

    "This is mostly just a thought experiment, but I am curious to see what other Slashdot readers could maybe dream up. In my opinion (and I'm sure many others as well) my current meatspace coordinates usually mean much less than my network 'location' does, but I can think of many times where proving my meatspace location could be just as important as proof of identity."
