On a related note, did anyone actually watch the press conference today, and if so was there anything interesting they had to say that wasn't already reported?
i did, it was as predicted mainly a 2 hour long ascertation that they used the proper scientific method for these experiments

That unit of measure is only standard in American games. Like starcraft time, it is not designed for real world usage. The primary purpose of the "Mississippi" is to allow others involved in the game to know when:
1. You're going to try to find them hiding in bushes and behind the house.
2. You're going to cross the line of scrimmage and try to smash their face into the ground.
3. I don't remember ever hearing it outside those 2 contexts, but if it's used it probably involves firearms.

Didnt see that anybody posted the actual link to the press conference VOD before:
http://cdsweb.cern.ch/record/1384486
THE VOD ISNT UPLOADED SO FAR, but once it is you will presumably find it there.

SUSY @ CRESST was much more interesting news than this imo.
but my guess is that both experimental results are caused by systematic errors.

Actually its the only speed attainable by massless particles. But you know, very little difference. If we discovered that photons actually had mass, no matter how tiny, we would then still have the cosmic speed limit "c", but it would no longer be the speed at which light travels, just massless particles. Photons can travel much slower than c when not in a vacuum.
Ok, ok, that is true. But I always just assume in a vacuum for anything relating to these physics areas as that is the standard. But I understand that not everyone would.
Anyway, if you don't assume in a vacuum, then objects overtook the "speed of light" a while ago.

They travel at c, but they don't move straight because they are reflected/absorbed/emitted by other particles. Their own speed is still c.

Nope. In space, the only real way to travel is to chuck stuff in the other direction. Conservation of momentum means that you have to eject your fuel fast, but it also has to have sufficient mass in order to actually have an impact. Since neutrinos have little or no mass, well... you do the math.
Not to mention neutrinos are notoriously impossible to contain or even direct (as their name indicates, they are neutral). Even if you produce them, they'll escape in all directions at once, nullifying any thrust. Hell, most of then travel through Earth without a sweat.

If this is in fact true, FTL communication is EZPZ.

The curvature of the earth is obviously not the problem because previous tests have shown the control for such an experiment as infinitely close to the speed of light. In addition, the curvature of the earth over 700km is such an invarying variable(think from chicago the louisville) That the change affected thereof is small enough to be ignored in these experiments.

I'm sure they'll implement neutrino broadband internet access *right* after they get paid name changes implemented 
I don't think this newfound knowledge will change much, if anything at all, aside from our understanding of the universe. As stated, neutrinos aren't going to/can't be used for thrusters, at least not in my lifetime.

What's the experimental limit on the difference between the speed of light in vacuum and the speed c in the Lorentz transformation?

It is quite a surprise that CERN is finding neutrinoes before light. I thought those scientist-types were very bound by their routines. Might be they will start driving cars next. Now that would be scary!
Thanks for the warning OP!
