The amount of RF you receive via skywave from a megawatt HF station still is orders of magnitude less that the RF you'll receive from an unshielded transmission line going to your lamp next to you on your desk. It's the proximity of the antenna that really counts, and in PLC it's too close for comfort imho. Also, the duration of exposure is constant with PLC.
There is such thing as signaling over drillpipe. Sensors in the bit send data back to the rig via the drillpipe...it's hardly what I'd call broadband though.
Also, power can be naturally generated in long pipelines by geomagnetic disturbances. Sometimes these induced currents are in the 100's of amps.
This is not just a problem with Web pages, it is a problem with all popular media formats today. How can we make sure future generations will be able to make use of any of our media? (makes me think of a buddy's magneto-optical drive...who the hell else has one) One solution is to actively copy from format to format as technologies change, but this requires constand upkeep throughout the ages. Relying on future generations to maintain our most precious information is not a responsible behavior for a culture.
Printed media, while having a low data/pound ratio, has managed to survive and span generations for centuries. I think the need for paper libraries cannot be forgotten. The challenge is distilling out what is worth keeping, and this challenge is better met now rather than later because we have more or less a good idea of what is significant information, and what is crap.

You no longer need your cubicle because someone in a foreign country now has your job at 1/10th the costs to us. Oh yes, don't bother going there because their country doesn't reciprocate and allow Americans to work there.
This is one more example of the American middle class being put out to pasture.
and the rule is "minimum power necessary to facilitate communications, 1.5kw max." BPL is going to raise the noise thereby legitimatly allowing amateurs to turn up the juice.
1.5kw through a 12 dbi antenna = 24,000 watts ERP. That's gonna be nasty for BPL devices too...
CLARIA IS SPYWARE....now come get me Mr. laywer, I dare you.
Since Gator Inc. is putting real money into changing their name, lets make sure that the term "Claria" is equated with exactly what they are peddling. Annoying crapmongering software that spys on what you are doing, sends interrupting ads, and slows your system/connection.
When you think "Claria," don't just think "Spyware," think "Turd-Ware"
There won't be much *NIX spyware simply because *NIX users are typically smarter, won't tolerate spy/ad/mal/scum/gator-ware, and are a lot more security conscious than the typical win-drones.
"...running on a 400MHz Intel X-Scale processor"
Surely this has enough horsepower to implement realtime voice encryption and authentication on. I wonder if the phone's digitized audio is available via an API.
This could really create a dependency on wi-fi
and one must remember wi-fi devices are FCC part 15 devices are therefore down the totem pole from the ham band at 2.4ghz. As a matter a fact, I can run up to 1.5KW at 2.4ghz provided this is the minimun necessary power to establish communications. (real example: moonbounce)
Is suspect if I was to run a 5W 2.4ghz TV transmitter, I'd interfere with quite a radius of 802.11b devices.
Wi-fi devices cannot be relied upon to provide mission-critical services, period.
I once heard that NASA was looking for sources of old 8086 (or maybe 8088) processors because certain aspects of the current shuttle design have been around a LONG TIME. I bet there are a lot of old workhorse embedded systems using very old processors.
An important sidenote to ideas like civil disobedience is the idea of jury nullification. Normally today, and judges want people to believe this, a jury rules on questions of fact and a judge rules on questions of law. This does not have to be the case, and there is historical precident of the jury basing their verdict on a question of law rather than a question of fact. If a jury rules based on what it believes to be an unfair law, then the court's decision nullifies that law.
I think a well-defined time-tested industry standard protocol like RS485 should be considered. RS-485 is a serial protocol that uses balanced signaling (good for noisy enviroments) and can handle multiple devices on the same wire.
I'd also add to this list: zipcentral (free winzip clone) Activestate Perl (gotta have a native perl) pegasus mail (hey, I like it) secure shell client from ssh.com (w/ drag/drop sftp) The Gimp (photoshop replacement) ws_ftp (oldie but goodie) ghostscript/ghostview (tech papers often in.ps) acrobat reader (pita to be without)
I have a small site that I wanted to list email addresses on and not expose them to harvesting, so I came up with a fairly simple scheme. Using PHP/GD, I wrote a script that would take an email address in the URL (obfuscated) and generate a png graphic of the email address. It's not clickable, but visible.
Just to note, I realize OCR could be used to get around this, but I've only a few addresses anyway. In the future, I may generate "messy" images that are difficult to process with OCR.
There is no reason why an air cooling solution would necessarly be noisy. There are plenty of ham radio rigs out there that dissipate a lot more heat than 103W, and do so quietly. What you also need is a large thermal mass on the chip regardless of cooling mechanism to prevent a rise in temperature too rapid to respond to in the event of a cooling system failure.
Why not just install cheapo receipt printers into the voting machines and keep a paper tally that would be easily verifiable if need be. This would be good for an audit, and a statistically proper number of voting machines could be audited to insure valid electronic reporting. Although crude, a paper record is nice in it's resistance to tampering (at least electronically). At work we've got a dot matrix printer hooked to the door's ID card reader. There ain't no hacking that without physical access.

Naive P2P is bandwidth hungry, but better protocols such as those implimented in bittorrent are actually pretty bandwidth friendly.
Actually, isn't it now more like "Would you like iFreedomFries with that?"
I can't because I run a real OS that doesn't have a provision to allow for "drive-by" downloads.

BonziBuddy is the epitome of all sodomyware...there's even a horny purple gorilla to boof your PC.
I think Gator has earned the right to be called much more than spyware. Lets call it sodomyware.

Closed family trees recycle DNA, and it eventually shows (i.e. Prince Charles).

This reminds me of a scene from Zoolander where one of the models gets a call on a postage-note sized cell-phone...
