  We digress on the implications of recent claims of superluminal neutrino
propagation. No matter how we turn it around such behaviour is very odd and
sits uncomfortably even within "far-fetched" theories. In the context of
non-linear realizations of the Lorentz group (where superluminal misbehaviour
is run of the mill) one has to accept rather contrived constructions to predict
superluminal properties for the neutrino. The simplest explanation is to
require that at least one of the mass states be tachyonic. We show that due to
neutrino mixing, the flavor energy does not suffer from the usual runaway
pathologies of tachyons. For non-tachyonic mass states the theories become more
speculative. A neutrino specific dispersion relation is exhibited, rendering
the amplitude of the effect reasonable for a standard Planck energy. This uses
the fact that the beam energy is close to the geometrical average of the
neutrino and Planck mass; or, seen in another way, the beam energy is
unexceptional but its gamma factor is very large. A dispersion relation
crossing over from a low energy bradyonic branch to a high energy tachyonic one
is also considered. We comment on consistency with SN 1987A within these
models.
