I don't think that it matters whether you convert to electronics or amplify with laser techniques. The cryptographic secret is kept in the quantum uncertainity of the state of the (single) photon. Anything that collapses that quantum uncertainity acts as a man-in-the-middle and stops the key/OTP generation. ------------------------------------------------------------------------ Bill Frantz | The CDA means | Periwinkle -- Computer Consulting (408)356-8506 | lost jobs and | 16345 Englewood Ave. frantz(a)netcom.com | dead teenagers | Los Gatos, CA 95032, USA

Piracy Bests ITAR
by nobody＠REPLAY.COM 17 Dec '03

17 Dec '03

The Economist, 17 Feb 1995, p. 17. Should foreigners' intellectual property always be protected? [Excerpts] Is it right to expect governments, especially poor ones, to honour new World Trade Organization rules on intellectual property? Some economists have made a good case that slack enforcement of such rules may sometimes do little harm. Local firms benefit by acquiring pirated technology more cheaply than the real thing; consumers acquire affordable high-tech products and close copies of branded goods. Although the original producers of the intellectual property lose out, it is sometimes hard to tell how much. They might anyway have sold nothing in a poor country at rich prices. And provided that counterfeiters make reasonably faithful copies, piracy is free publicity: how many Chinese would know about Microsoft's latest programs, or listen to Michael Jackson's new album, had they not been able to buy illegal imitations? ... It is not always obvious what theft is. Much in patent and copyright law is arbitrary. But who says American copyright law is correct? More to the point, why should China accept America's view of how a drug design, say, should be accorded patent protection? In some cases, the interests of rich and poor countries are clearly at odds: one side has all the property. There seems to be no objective standard to appeal to. Eventually, this may change: as poor countries produce more innovations themselves, their own inventors will demand greater protection. Meanwhile, the lot of many intellectual-property producers will not be a happy one.

And an awful analogy (not entirely worthless, but not very good either). Has nothing to do with socialism... even works nice in a capitalist as in the case where people try the software, decide they like it, and then buy it latter when they can afford it. Sidekick and WordStar became popular because of this "borrowing". MS-DOS probably would not be so widespread if it weren't pirated. Oh yeah, patents as well...
