An off-topic quickie rant regarding "essential services" and "qualification"... I notice in the current tax-cutting climate (at least in the US) that people who resent it when garbage collectors, janitors, teachers, train conductors, etc. are making a "decent" wage because they have to pay the taxes and fees (private as well as public) for these services. They seem to view the fact that they have a college degree makes them more entitled to a reasonable standard of living than a high-school drop-out... Yet in terms of supply and demand economics, perhaps garbage collectors etc. deserve to be paid more than accountants and salesmen... This has nothing to do with cypherpunks or himalayan hackers in hot tubs, so back to the usual data trash. - --- [This message has been signed by an auto-signing service.

Woooa there.... Lasers are not exactly expensive or complicated.... Check out www.lasercomm.com. 4-15Mb/s lasers. or Cannon 10-100Mb/s lasers. I have installed these products *many* times and their setup and operation is fast and efficient. (used to work for Interop) Exmaple: We used a pair of these, and MBONE, to provide a 2 way real time video confrence link joining an IETF session between a room of users at Japan Interop (local) and a group in Sweeden (IETF). The setup a was last minute point to point Ethernet link from the confrence center to a local hotel acress the road. We had 1.5 hours to perform ALL of the work, from wiring both roofs, seting up the lasers, wiring the internal hotel/confrence center, and setting up systems and projectors. !!The Laser setup took about :15 minutes, tops!! BTW: With this system the transmit "beam" is focused into a "spot" half way between the sending and receiving units. The receiving unit is tuned to look for that focused "spot". This means that there is a very large (area wise) low power laser pattern behind each of the receivers! With a sensitive enough receiver, it is possible to hear this signal! When you need to transport a data stream (1-155Mb/s) to a remote site, this solution works out to be *MUCH* cheaper than leasing circuits from bell, bypass folks, etc.. Another case in point: We (ISN) needed to transport a 100Mb/s (FDDI) between \ 2 sites. Upon checking, the price of PacBell "dim" fiber was outrageous! We had no MFS/TCG/etc fiber in the man hole to latch onto. The choice was clear. As for security, the bottom line is that encryption devices are cheap. Last plus for these units is that most foreign countries do not prevent the use of these point to point optical devices. This is not the case for spread spectrum multipoint or microwave point to point radio devices.

In the last Indian war (the Modoc war), the Indian leaders were hanged as common criminals when the war was over. The current law allows small sins on the reservation.

Indian Reservations
by Greg Kucharo 17 Dec '03

A indian reservation sure beats moving to the Turks and Caicos. Well maybe not the weather part, but anyway in recent times I believe that several local governments have challenged the indian gaming enterprises. I recall a report on NPR about a challenge in Deleware or New Hampshire by a group of townspeople that was on the edge of a reservation. The indians won the case and were allowed to continue. Because of the new wealth generated by the bingo parlors and poker tables, the various tribes have gotten lobbying power in Congress. So I think that indian reservation sovernignty has grown in recent years, and would be very intresting course to pursue. -----BEGIN PGP PUBLIC KEY BLOCK----- Version: 2.6.2 mQCPAzEIa2wAAAEEALouE7MNxsG+QTOJSrMTygYWKblpI9MgOKaFA+5AICNelAw6 6Gj3B0EQr7bwLILk8EJULG+kYh/ND9Kn1EXBK+elXbwpFCLqoyEZrbHJnurhH/t6 VFEwhbN1V0e/bFOCTq8nykoJjZ/uq0mz8HouIbEt6BYWoKVSUIU/T+iDV3TVABEB AAG0DWdoa0Bzb3BoaS5jb20= =gwax -----END PGP PUBLIC KEY BLOCK-----

Oh, but it is done very, very often. That is, it is not something reserved for "war criminals" (not that war criminals are excluded, as shown by the Dayton Accords, and other visits.) "Denied entry" and "undesirable" are the operative words. The offense may be writing materials critical of the U.S. (poetry, novels, etc....so far, not Net stuff). Various flavors of activists, writers, critics, etc. are often denied visas to enter the U.S. I don't believe the Net has yet registered on the Richter scale of visa grantings, but I suspect it will within a couple of years, both because the Net will become a more important media channel and because it will be so easy to compile lists of folks who will be denied entrance visas. (And the same applies in reverse. I have no doubt that I will be denied visas to enter various countries, including the freedom-loving countries of the mullahs and sheiks, and that country which sent Pollard to spy on the U.S. Good thing I don't want to visit any of them, except Iraq.) --Tim May Boycott espionage-enabled software!

The texts say a >combination is a good idea. Well, for a well funded adversary, the first step is to buy a duplicate to the system to be subverted and analyze it. Usually is nnot difficult. Problem with biometrics is the cost/speed. To do it right is going to be slow/expensive. Few are. However the traditional rule has been "something you have/something you know" two factors are good, three are better. In that line, along with one of my primary tasks (securing of notebooks) have been warning people that if the information is valuable enough to require that level of protection then the user is put at added risk the same way that better automobile locks spawned carjackings. Duress codes are not difficult to impliment. BTW voted for Ed Clark once since "none of the above" was not an option. Spent the next year getting beg letters from various libertarian groups.
