At least two news stations in San Diego said that the Mexican border was open, but they were carefully checking all incomming traffic. The border wait was at least 2 hours.
They also said that no commercial ship were being allowed into the harbour at this time
I am not a string theorist, but when string theory talks about 10 dimensions it is usually understood to mean 9 space-like dimensions and one time-like dimension. Now time-like dimensions are inheriently differenent than space-like dimensions, and that is what special relativity deals with--the wierdness of the time-like dimension.
Actually we already have those. Erbium doped fiber amplifiers have been used for a while to combat the attenuation of fibers. They are simply a segment of fiber that has been doped with erbium and are then pumped, this then acts as an optical amplifier. I believe semiconductor lasers used to be used for this, but that was probably about 10 yeas ago.
The difficulty with optical routers is trying to process and split the data optically.
I went to a talk a year or so about this. (Although I can't swear to get all the details right.) There was an american researcher who said he was approached by some russian scientists if having isotopicly pure Si would be usefull. Apparently after the USSR disolved it was decided that they didn't want all the people who knew how to separate isotopes to be unemployed and the machinery to appear on ebay so they went down the periodic table producing isotopicly pure elements.
Because it is so hard to do, isotopiclly pure elements are very valuable, but it is also very hard to find a buyer, so the Russians were nearly giving it away to researchers.
As to whether this can actually be used to make faster Athlons though, I agree I am in the "ait and see" catagory.
The route between san Diego and LA might be high traffic enough to work here on the West Cost. Unfortunatly the concept of not driving is so foreign here there won't be a bullet train built in a long time
disclaimer: Although I don't do optics anymore and am just a grad student I used to work with similar (mathematically) stuff.
I read through the paper and would have to agree with you. The paper seems correct after a quick reading and all of there approximations are fairly standard (e.g. I would have to agree that the shouldn't be need for any thing above gain-velocity dispersion) Also, they said they did do a numerical simulation and got result similar to seen in the experiment. But I could just be biased because I do computational physics:-)
More interesting is that there were experiment earlier showing superluminal propagation of information on microwaves I haven't seen the original paper (nor do I have links) but supposedly they were able to hear music at 1.2c. The basic affect was caused by the microwaves tunneling though a barrier.
I'm not sure if it does shading very well but xmgr is a good free plotting package. I don't like the interface as much as matlab but it is free and can do some things matlab can't.

As I yearn for the Teddy Roosevelt Republicans of yesterday.
