There are a couple of reasons why security at the media layer is being looked at for 802.11, specifically 802.11i (Task Group I) is specifying use of encryption such as AES at the physical layer. A main driver is that low powered devices like phones, PDAs, etc. do not have the computing power to do this in software and do robust encryption at high data rates. Adding security at the chip level will help to keep power (cpu and battery) requirements down.
To respond to your point about firewalls, that is hard to do and still provide public access hotspots. You are right that protecting things at a high level is a good thing (tm) but you still need protection of the link itself.
Here is a better remote http://www.theonion.com/onion3104/newremote.html
TOKYO--Television watching became even more convenient this week with Sony's introduction of a new remote-controlled remote control.
The new device, which can be controlled via remote control through the use of a second remote control unit, will replace older models that needed to be held in the hand to be operable.
"Constantly leaning forward to pick up the remote control from the coffee table is a tiresome, cumbersome chore that will soon be a thing of the past," Sony director of product development Dan Ninomiya said. "These new remotes, should they be left on the coffee table or in some other barely-hard-to-reach place, will not need to be picked up and actually pointed at the screen in order to work."
The new remote control--along with the additional remote it is designed to control--will soon come standard with all Sony televisions, allowing viewers to remain "more immobile, more stationary, and more physically inert than ever before."
"Imagine a remote control capable of switching channels on your television right from its spot on the table, one that requires no clumsy fumbling about with the hands to operate," Ninomiya said. "Well, that bold, inactive future is here."
The Sony remote-controlled remote control, or RCRC, also puts an end to worries about losing the remote in the couch.
"The RCRC works from anywhere in the room, even deep inside a hide-a-bed sofa," a Sony press release read. "This puts an end to distracting remote searches, frustrating lifting and stacking of cushions, as well as eventual cushion replacement after retrieval, an annoying task that can sometimes result in missed programming and, in some cases, serious waste of valuable television-viewing time."
As an added convenience, in the event that the RCRC itself is accidentally placed in a less-than-immediately-accessible spot, it will come with an additional third remote control.
"Should the second remote end up under a magazine or newspaper, the third remote will still be capable of controlling the second remote, enabling the second remote to change channels on the first one, and ultimately the television itself, with just the touch of a button," Sony spokesperson Rich Hervey explained. "Regardless of the location of the remote control unit, the ease and comfort of remote-control television viewing will be assured."
To ensure that the third remote is not lost as well, it will come with a handy adhesive pad affixing it to the owner's forehead at all times. Or, in the case of more expensive models, it be implanted directly within the sinus passages of the user.
"This," Hervey said, "will make the loss of the third remote control a possibility that is, at most, remote."
Home entertainment industry insiders predict that the new RCRCs will be hugely successful.
"These things are fantastic," said Seated Viewing Magazine editor Ted Kohrs at a recent Las Vegas trade show demonstrating the new product. "I've been here all morning and my heart's only beaten six times!"
It is believed that the new Sony remote may prove even more popular than competitor Toshiba's new Pepsinjection intravenous soda-drip televisions as the hot home entertainment item for 1997.

I used this last year as a interview techique for Semiconductor Applications engineers - EE's and embedded programmers. I gave them about 2 1/2 hours and 1/2 hour to talk about it and then I took them to lunch.

Exercise Instructions
Dear Candidate,
This exercise is intended to break the monotony of the standard interview questions like "Tell me about your strengths and weaknesses." Please read this document thoroughly before you start!
Your instructions are simple: Build something using the Lego Mindstorms Robotics Invention System and then tell us about your experience!
There are no constraints on the simplicity or complexity of your project though you are expected to do programming as well as mechanical assembly. You are free to use the examples in the kit or the provided documentation (O'Reilly Mindstorms book) as a starting point.
System Setup
The computer has the Lego Mindstorms software loaded and tested.
The firmware has been loaded into the RCX module and tested. COMM 1 is working for the IR Module connection. Batteries should be good (let us know if you have system problems - they are not part of the exercise!).
In addition, on the computer is an additional programming system called RCX Command Center (Version 3.1) that uses NQC (Not Quite C) and a graphical interface for programming. This has also been tested and documentation is provided. You are free to use either the Lego software or RCX Command Center for programming your robot. The CD-Rom case has instructions on how to bypass the Lego Tutorial.
Presentation
At the end of the exercise you will give a presentation and demonstration (5 -10 minutes) of your project. Feel free to use the whiteboard and/or flipcharts for your presentation if needed. Please address the following topics in your presentation:
How did you set about the exercise in terms of planning, architecture, and construction?
What did you intend your robot to do and what does it really do? Why?
What obstacles did you encounter during construction? How did you overcome or bypass them?
What would you do different if you were given another session?
There is no "right answer" to this exercise and there are no hidden tricks or traps. The intent is to give you an opportunity to show your creativity, learning skills, problem solving, time management, and explanation skills in a different way.
"Guns don't kill people, people kill people." As much as I hate to say it, they're right.
No they are not - "Guns don't kill people, bullets do - guns just make them go really fast!"
But seriously -
""Did you really think we want those laws observed?" said Dr. Ferris. "We want them to be broken. You'd better get it straight that it's not a bunch of boy scouts you're up against... We're after power and we mean it... There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws. Who wants a nation of law-abiding citizens? What's there in that for anyone? But just pass the kind of laws that can neither be observed nor enforced or objectively interpreted - and you create a nation of law-breakers - and then you cash in on guilt. Now that's the system, Mr. Reardon, that's the game, and once you understand it, you'll be
much easier to deal with." ('Ayn Rand - Atlas Shrugged' 1957) "
The Cybiko is a handheld "kids" PDA that has a 19.2 kbps, 900Mhz wireless connection that supports up to 99 users in a range of 300'. They don't seem to be selling much but it is an interesting platform, just marketed wrong IMHO.

I think it is great sport to go into the WiffyBurger and using your example of $2.53, give the clerk $10.03.
Last time I was at a place and did that the electronic till was down and the clerk had to have the manager explain why I gave $10.03 and what the correct change was. It took 5 minutes to get change.
On another note, remember that Mattel had to take the talking Barbie that said "math is hard" off the market!
One of the major reasons for the slow adoption of FireWire has been the issue of copy protection. Almost all of the PC cards use what is called the
OHCI (open host controller interface) to connect the 1394 bus to the PCI bus. The 5C license specifically prevents unencrypted video data from being put onto a "public accessable" bus so it is hard to get content to the graphics card or CPU for MPEG decoding.
5C does support copying, it depends on how the data is flagged. Content can be marked "copy freely", "copy once", "copy never", and provisions (as I understand) are being made for time shifing.
Firewire w/5C was planned for consumer electronic devices and chips like the one from Philips are aimed at that market. There have been designs on the books for years but without digital content from the MPAA there is no need for additional expense in DTV, STB, DVD players, Tivo, etc. - a chicken and egg situation.
Firewire is good technology but without the volume the chip/implementation cost will remain somewhat high. Without content, it doesn't matter what speed it runs at, there will not be much data that needs the speed...
