They would be moving away at the speed of light from any reference point. One neutrino would "see" the other moving away at the speed of light.
If you stood between them they would both be moving away at the speed of light from you. If you shot one away and then accelerated to the speed of light in the other direction then that neutrino would still be moving away at the speed of light.

Yup, you got it.
My previous answer is technically incorrect in the sense that "objects" at light speed don't really experience time anymore, but people have a tendency to ignore that bit when trying to explain relativity in hypothetical examples.
