Hello Mr. Bennet.
Welcome to our site: you are our first customer from Buderim, Queensland, Australia.
You have an interesting suggestion but there are several problems in replacing the velocity of light with the velocity of neutrinos as a standard.
1. The OPERA experiment may be wrong. It is the only one in which superluminal neutrinos have been detected. Other experiments both at CERN and at Fermilab are planned that will verify or refute that result.
2. The best relevant experiment I know of is the concurrent observation of both neutrino and light induced flashes from a very distant supernova explosion SN1987A. The neutrinos were detected in the Japanese Kamiokanda detector and others in the US and Russia. If the neutrinos had traveled at the same speed as the CERN neutrinos they would have arrived months earlier. See the nice discussion of this at: http://www.centauri-dreams.org/?p=19912
3. One can argue that the supernova neutrinos were of rather low energy whereas the CERN neutrinos were much higher energy and that makes a difference. If so then that precludes the speed of neutrinos as being a standard. Lorentz invariance is violated and speed of "neutrino light" would depend on which inertial frame you were in. Not good for a standard.
My personal belief is (and I very much hope so) that the OPERA result is flawed in some way. The systematic errors in the timing are very subtle and involve corrections due to general relativity effects. Keep tuned.
Feb. 22: By a coincidence, just today the news came out that a loose connection in the experiment caused a 60ns timing error. http://news.sciencemag.org/scienceinsider/2012/02/breaking-news-error-undoes-faster.html?ref=ra
It could turn out to be that simple. Mike W.
