US Falls to 25th in Broadband Penetration Worldwide
US high-speed Internet is slow compared to other countries. The average broadband download speed in the US is only 1.9 megabits per second, compared to 61 Mbps in Japan, 45 Mbps in South Korea, 18 Mbps in Sweden, 17 Mpbs in France, and 7 Mbps in Canada, according to the Communication Workers of America. For example, 80 percent of households in Japan can connect to a fiber network at a speed of 100 megabits per second. This is 30 times the average speed of a US cable modem or DSL connection, at roughly the same cost.

Radio Frequency Tags
Hitachi Develops World's Smallest RFID Chip. It has 128-bit ROM for storing a 38 digit number. They have been used to prevent ticket forgery. The RFID 'powder' is so much small it can be incorporated into thin paper, like that used in paper currency and gift certificates. After swallowing a tag a patient need only sit next to a radio source and receiver and they stop working when exposed to gastric acid for a specific period of time, providing a subtle way to monitor a patient's digestive tract. Similar radio tags could also be embedded in an artificial knee or hip joint in such a way that they disintegrate as the joint does, warning of the need for more surgery.

The RIAA's moral argument about P2P file sharing
The RIAA says it's immoral to file share, if that's true, then how about industry price fixing, copyright extension, radio station consolidation, and refusing digital distribution.
PeerMind registers millions of file-sharing events every week, and you can see the aggregated results on this site
RIAA: Piracy is bad for us, but legitimate sales of music online is bad for us, too
