Whoa!  Neutrinos most definitely can interact with photons of any
wavelength.  After all, neutrinos have a magnetic moment (very small,
not yet measured, upper limits only known so far) in the Standard
Model.  Think of it this way - every neutrino spends part of its life
looking alot like a W-lepton pair. 

And photons get involved in weak interactions through trilinear and 
quadrilinear boson verticies, so even in first order some unfamiliar
processes can lead to neutrino-photon interactions.  For example,
neutrino + photon -> lepton + W* + photon -> lepton + W.

The problem with detecting this process and many more is an experimental 
one,  not a problem in principle due to absence of the interaction.
