Police will patroll the voting places for the Dutch national elections extra carefully on November 22nd in order to prevent spying.
The SDU machines that are now banned could be monitored from 120+ Feet (40 Meter). The more common (in the Dutch elections) but not yet banned Nedap voting computer can be monitored from 15 Feet (5 Meter). So the Dutch police will be on the lookout for anybody close to the voting locations with an antenna sticking our of their pocket;)
It totally depends. There is still a lot of experimentation going on in Amateur Radio. The problem as I see it in the US is that there are a lot of "islands" of activity. Most US Hams I come across are too involved in their own world and will take a long time to accept outsiders.
For example here in Palm Beach County, FL. There is a reasonable active packet group but most of the equipment still runs on 1200 baud and some links are on 9600 baud. In Europe 76K2 Baud is almost the norm with some links even running as fast as 1M5 baud!
I suggested experimenting with higher speeds but no one here wants to help.
Another great opportunity for experimentation is Digital Amateur Television. Again in Europe there have been several D-ATV repeaters that have been active for years while here in the US D-ATV is just starting.
In conclusion:
Do I still find Amateur Radio interesting? Yes, but it depends on where you live and what other Amateur Radio operators are doing around you.
I don't think that this will wipe out 802.11b. Because of other Amateur Radio usage in this band the Amateur Radio version of 802.11b will be fixed to one channel (6). Regular 802.11b devices will automaticly switch to other channels with less interferance.
Why ham?
For me it is because I can build everything from scratch if I want to.
Another reason is that the ham community still innovating.
Maybe this experiment will generate a better understanding of the interferance that is caused by all the users of the spectrum and even come with solutions that can be used for the regula part 15 801.11b devices.

The effort, called the Commemorative 9/11 Net, is being spearheaded by Len Signoretti, N2LEN, of Brooklyn, New York. N2LEN's 440.050 MHz (CTCSS 114.8 Hz) internet-linked repeater covers the Greater New York City area. The linkup will rely on either EchoLink or eQSO Internet software connections. Signoretti said his UHF machine is used as a central hub to coordinate EchoLink and eQSO, so users on each can communicate. The net will attempt to interconnect repeaters in all 50 US states as well as in many other countries around the world.
Amateurs can download free EchoLink or eQSO software from the Internet. While there is no listen-only capability on the Internet, many local VHF and UHF repeaters are expected to take part in the commemorative linkup.
The Commemorative 9/11 Net is scheduled to get under way at 8 PM Eastern Daylight Time (0000 UTC September 12) on the EchoLink and eQSO servers and could run as long as two hours. Haynie (ARRL President) is scheduled to address the cyberspace and RF-linked gathering at around 9 PM EDT.

The amateur radio club of the Florida Atlantic University, K4FAU and the Boca Raton Amateur Radio Association are having their combined Field Day on the ropes course of FAU in Boca Raton. Here is a map of the Boca Raton Campus. The ropes course is indicated with the number 74. Everybody is welcome to visit us.
We will have a special G.O.T.A. (get on the air) station running where you can operate a radio under supervision and can see, feel and hear for your self what Amateur Radio is about.
On Friday, March 1st, 2002, two Californian Amateur Radio Operators communicated over 175.3 Km (almost 110 miles!) using home build 75 GHz equipment. You can find an article here.
The fact that the military is not interested in this band might not be the difficulty of building the equipment, but the in the difficulty of operation and / or the reliability of the connection.
Just my $0.02
According to this article (in Dutch only) Belgian unions (their members) are not going to shutdown the NOC in Hoeilaart(B). They have come to an agreement with the curators.
The curators have offered 40 employees a 5 week contract so the NOC can stay in operation with a skeleton crew. Employees of other NOCs ( 200 in total) around Europe were offered similar contracts.
3G providers in Europe are going to charge their cutomers per byte not per minute. They will look at raw data so their will be no differance between surfing and a voice call.

World wide interferance???? I don't think so. 2.4Ghz is line of sight communication. If you want to get past the horizon there are to my knoledge 3 options: 1) Tropo scatter. Aim your antenna towards the tropo layer of the atmosphere and aks the receiving end to do the same. 2) Sattelite. I don't think AmSats are WiFi enabled yet. 3) Moon Bounce. Aim your antennas toward the moon and hope some of your signal makes it back.
But still.....DO NOT modify any RF equipment if you don't know what you are doing. RF can kill, even low power. On the right frequency you can change someones pacemaker settings!

Just get you Amateur Radio license and start bouncing signals off of the moon. http://en.wikipedia.org/wiki/EME_(communications) http://www.nitehawk.com/rasmit/ws1_1.html An other option is watching "free to air" FTA TV channels. If you like to channel surf just Google FTA receiver. A good receiver plus C-Band (or C/Ku) LNB will cost about $200.

The first computer I used was a Philips P2000T.
The first computer I owned was a Timex Sinclair 1000.
A couple of weeks ago I attended a SkyWarn class and noticed that the NOAA trainer was using FireFox on their NOAA issued laptop.
I'm guessing one of the men is David Beckham and one of the women is Victoria Adams (Posh Spice)

Although the articles are a bit thin on specs my gut instinct tells me it will be similar or an improvement the EH antenna. Link to definition (pdf) of EH antenna Link to (pdf) how to build an EH antenna.
I hope that despite of the patents the design will be made available for amateurs to use and experiment with.
These kind of innovations just show that Amateur Radio is still alive and can contribute in the advancement of radio.
Amateur Radio also still works for emergencies.

Let's hope that they rebuild with something better and newer.
