Not much to say. ADSL, very reliable, faster downloads than rated (about 3x); uploads go at the rated speed. Occasional routing problems render some parts of the net inaccessible; these usually clear up within 1 to 2 hours.
Installation was done by SW Bell's rep... has worked great since installation about 4 months ago. Not a plug, just my experience...
Yes, CueCat's method of scrambling barcodes is childishly simple. But there would be little point in implementing a stronger algorithm since an attacker would have an unlimited number of plaintexts available and could generate chosen plaintexts at will. Any algorithm that would be feasible to implement in a piece of giveaway hardware would be vulnerable to attack.
Yes. They could emit sound waves. But the craft would be traveling faster than sound. The craft would arrive at the obstacle before the sound. If a predefined lane of travel were kept clear by a series of sound-emitting buoys, however... presuming that a sound could be tailored to repel creatures large enough to be hazardous to navigation. Sharks, etc. might not be repelled by sounds that repel dolphins and whales. Such a series of buoys might also have the effect of interfering with the migratory patterns of some marine fauna.
Theodore Sturgeon also wrote a short story along this vein, called "I See You." The results to society were exactly as the last paragraph of Sebastopol's posting described. In Sturgeon's story, the invention was immediately released to the public domain anonymously... the inventor used two mailing labels, one obscuring the other, with special glue so that the one on top would fall off during transit. He was able to conceal his identity until he was safely dead...

You said: (I know I will not gain any points of friends by saying this, but I must speak my mind.)
Actually, you were speaking Ayn Rand's mind. Not your mind; Ayn Rand's mind.
There is a difference.
