Have you seen Series 7: The Contenders? I highly recommend this to anybody interested in reality shows and how they will end up.. The Contenders show is about killing people. The show people just give randomly chosen people guns and the goal is to survive by killing all other contenders..
This is done routinely here in Europe. Heck, I work at an ISP that does exactly this (wireless Internet over 2.4 GHz ISM band).
Add antenna gain, substract some interference and there you go. The only thing you have to care for is your country limitations for transmission power in the 2.4 GHz band (which is the band all these things like Lucent WaveLan, Cisco Aironet or BreezeNet use). It is usually defined as EIRP (Equivalent Isotropic Radiation Power), which means for you the more you gain with the antenna the less power you may feed the antenna..
With more browsing devices, the manufacturers unfortunatelly tend to create new protocols. Look at WAP with mobiles. I would *love* to have HTML browser like lynx in my mobile, but instead I got WAP. It is very, very sad..
Well, Bruce Schneier has a nice story about
somebody pretending to work in a dotcom without
anobody noticing he's there without being employed
there at all! Read it at

down to Social engineering at its finest..
Well, I guess anybody can use the same DSS chips as the big makers use (WaveLan, Arlan) and some Ethernet bridge chips to have a nice wireless Ethernet device..
Did you realize you may be breaking your country's laws? There's a regulation saying how much power, computed as EIRP (equivalent isotropic radiation power) you can use when transmitting in the public 2.4 GHz band. Here in Czech Republic it's 100 mW (22dBm), which is also the ETSI norm. I believe it's the same in Germany. The maximum power level is counted as equivalent of an ideal isotropic antenna, so if you transmit at say, 4 dBm, and add a 24 dBm antenna you are at 4+24 dBm, exceeding the maximum by almost 50% ! With 1.8m parabolle, you could be well over few Watts.
And there's nothing special about it.
I happen to work at an ISP, which does exactly the same (InWay), i.e. building a wireless network from BreezeNet's with external antennas, which were designed for office-wide
wireless LAN originally..
It's pretty common alternative to expensive land leased lines from monopolistic Telcos here in Eastern Europe, these ISPs have 1000s of customers.
BTW, it's not very wise to build such a network based on DSS (direct spread spectrum) devices (like WaveLan) where FHSS (frequency hopping spread spectrum) devices are also allowed in the same band -- FHSS always wins the interference duel with DSS, because DSS sends the same data still at the same frequency, while FHSS hops over all the band randomly.
There's also a very cheap (some $250 for both ends) device from Siemens called Gigaset M-1000 Data or something like that. It's a serial port version of a wireless phone It just extends a serial port (V.24, 115200 bps) over cca 500m distance, with external antennas maybe even more.

Well, apart from easy manipulating with results
(there will be one central deposit, right?:-), the protocol for electronic voting is very difficult, with many almost contracictory requirements (like, only registered voters can vote, nobody can vote twice, yet nobody must know how each individual voted). For example, in the scheme proposed by jamie, I can vote as many times I want to, because the logs are erased. Bruce Schneier has whole chapter on electronic voting protocols in Applied Cryptography.
Try entering a nonexistent domain name at bordercontrol.com, such as apdokxxas.com -- it gives (at least to me) USA, Japan, Canada, Germany or nothing on random.
This should be used to authenticate country of origin?
From the article:
Fenton [the system administrator(sic!)] said he has tried many times to fool Border
Control, but has yet to outsmart its massive database
of Internet protocol (IP) addresses linked to geographic
information. (Web surfers can test the technology
themselves at http://www.bordercontrol.com/ )
And keeping geographical info on IP addresses in an apparently static database?
I can't explain all this otherwise -- it is just a joke. I don't know, who made the joke though -- 32bitsonline, this JumpTV, or the authors of this "Border Control".
Try to check them with 10.0.0.1 or 192.168.0.1.
You are in -- Netherlands!:-)
Besides, if you use an anonymizer or a proxy
server, it is its IP address, not yours that applies.
A snail-mail letter sent to your real street address in the right area with some activation code would do much better than this silly check..
Of course, then you ask your aunt in Montreal to forward this letter to you and you can see her TV channels etc..
There's another bug in Nokia 7110, which does in fact work.
Want do DoS your friend's Nokia 7110?
Just send him a calendar note from Nokia 6110 via a SMS. The calendar in 7110 will stop showing calendar notes. This works at least with firmware 4.84, I didn't check any other versions.
I wonder if we will live up to buffer overruns in mobiles.:-)
In Europe, and probably in GSM in general, you don't pay for inbound SMS messages or calls. Given you also don't pay for E-mails sent to mobiles from Internet, it gives spammers very good perspective..:-(

Well I haven't been watching the recent inflation figures in the USA, but do they have already $10 coins? And how big is that, then?
Like http://www.movieflix.com/ or http://www.ifilm.com/. They carry much more and much better films (lots of feature films since the silent era till cca 50's).
