Maybe if I ever show up for a flight really early I should come prepared with some ice in one container, and some liquid nitrogen and argue that at least one of the two should be let through...
My understanding is that dry ice is permitted in quantities greater than 100ml, but not in large amounts. I think that the pressures required to keep nitrogen/oxygen in a liquid state would not be permitted for travel by aircraft.
