      Now, on the Internet, it's very hard to enforce certain kinds of laws unless you build in architectural constraints. We can have a debate as to whether or not the law should exist, given the costs of enforcing it within a certain set of architectural constraints. But, you can't argue that a law doesn't exist, or shouldn't be followed because there is no architectural constraint (actual code preventing you from doing it).

      That kind of thinking will lead to laws declaring certain architectures legal, or illegal, so it will be impossible not to follow the law because the architecture makes it impossible.

    Tapping the alpha geek noosphere with EtherPEG

    by Rob Flickenger
    May. 15, 2002

    So there I was at ETech, sitting in the back of the Emergence discussion, listening to Rael Dornfest, Cory Doctorow, Clay Shirky, and other extraordinary blogging minds thought about the blogging world.

    I was thoroughly enjoying the discussion, but I had to wonder, how were the other 200 people in the room reacting to the proceedings? Response seemed very favorable, but I did see quite a few faces staring down, with accompanying tell-tale key clicks buzzing about the room.

    If only there were some way of getting into the collective stream-of-consciousness of the crowd, to gauge their actual reactions to what was really going on up on stage...

    If you've never heard of EtherPEG, its a Mac hack that's been around for a while that combines all of the modern conveniences of a packet sniffer with the good old-fashioned friendliness of a graphics rendering library, to show you whatever GIFs and JPEGs are flying around on your network. It's sort of a real-time meta browser that dynamically builds a view of other people's browsers, built up as other people look around online.

    The effect was staggering. As I expected, traffic was very light at the beginning (a couple of big news and blog sites were obvious, and strangely enough, the Microsoft Developer's Network.) But as the talk continued, some people were obviously letting their minds (and their fingers) wander...

    Early traffic showed a very wandering bent.

    I was impressed that when Tim O'Reilly stood up to ask about whether bloggers were building a city or living in their own ghetto, virtually all traffic stopped. Evidently, this was something that almost everybody in the room was interested in listening to. And once Tim sat down again, the pixels began to flow once more.

    After a little while, the atmosphere took on a bit of a dark turn. Lots of images of law enforcement agency websites, some american flags with an angry eagle bursting through, and possibly darkest of all, a Britney Spears fan site. The theme continued as Clay Shirky was discussing "maps and non-player characters" and the downward gothic spiral expanded...

    Further down the spiral

    It became obvious that the crowd could be viewed as a living organism, with its own cycles of activity and rest. The chaotic effect of random images plastering themselves on my screen gave me a unique point of view-- it was a sort of mental feedback (much like audio feedback, even with the accompanying headache, only this headache was in some bizarre fourth dimension.)

    The End

    By the end, the dark forces had definitely descended. I was treading on some very dark back waters of the collective geek subconscious... Think Evil Dead and PDAs in Washington DC. I had definitely descended into a sort of techno hell, the sixth circle of hades, where the damned are only given t-shirts after they listen to a short marketing presentation.

    EtherPEG isn't for the faint of heart, especially at a technical conference. The gentleman sitting next to me leaned over and inquired about how he could prevent me from watching his traffic... The technical answer is easy: run application layer encryption (ssh tunneling, vtun, ipsec, pptp) to a point outside of the wireless, and then your traffic will at least be protected from neighboring wireless eavesdroppers. But the philosophical answer is much simpler: I have stared at the sun, and for the sake of my sanity, will never again look directly at the consciousness of the online ueber-geek collective.

    Unless I really want to...

    Actually, it would be reasonable of you to view it as private- because you took some sort of measures to ensure it was not directly visible, you encrypted it with something. Doesn't matter if you use IDEA or a Captain Crunch decoder ring- you have some reasonable understanding that it's supposed to be private between you and those you're communicating with. Just because you can unpack it without effort means little in regards to privacy- you took some measures to obscure your communications so that they'd be private.

    If you take no precautions, it becomes much more of a grey area. A telephone conversation (not mobile) could be deemed as private because under normal circumstances, only the people involved in the conversation could really be listening (normal, being not wiretapped, etc.). A typical mobile phone conversation, however, is much more analogous to a CB channel or you shouting your head off in your house with the windows open than a standard telephone conversation (No matter how much the mobile companies want you to think of it like a magic phone, it's still more of a radio than a phone in almost every sense of it's operation.). In that case, no real measures have been taken by anyone to obscure the content of the conversation going on over the airwaves.

    There is no assurances of privacy involved in either of those cases, and unless you're using a digital spread spectrum phone (something making the session more resemble a wireline conversation- tougher but still not really obscuring it in a way that can't be snooped...) or encrypting it (preferably both in light of the previous aside...) you're operating under conditions not unlike the CB situation- whether you realize it or not. Ignorance of the conditions you're operating under doesn't make it any more a privacy protected situation.
