If we add the speed of the earth into the equation are Neutrinos going faster than the speed of light?

I came across a good post on a site that would never even allow me to ask questions on. http://www.physicsforums.com/showthread.php?t=151814 Even though it is managed by snobs I do find out some interesting info on it. From Jorrie about halfway down the page

“You obviously realize that speed and velocity are relative things. The closest we can come to determining our velocity relative to the universe at large, is to measure the temperature of the cosmic microwave background (cmb) radiation in all directions.
An observer that measures the average temperature to be the same in all directions can be considered as at rest relative to the cmb. As determined by COBE and WMAP, we are moving in the order of 0.1% of the speed of light relative to the cmb. This is due to the vector-summation of the velocities that you mentioned.”

So if from CERN’s own site http://press.web.cern.ch/press/PressReleases/Releases2011/PR19.11E.html    They state that the ““The ICARUS experiment has provided an important cross check of the anomalous result reports from OPERA last year,” said Carlo Rubbia, Nobel Prize winner and spokesperson of the ICARUS experiment. “ICARUS measures the neutrino’s velocity to be no faster than the speed of light… ” If this means that they are as fast and if the earth was moving away from the previous mentioned observer could it be measured as going faster than the speed of light? Or if some other observer was on a planet moving away from us would they observe the neutrinos moving even faster?

I still can’t get over the fact that even Jorrie states that speed and velocity are relative yet we have made a universal speed limit of a velocity regardless of the observer’s frame.
