The general starting point seems to be that a light saber would be based on something like a laser - which is where one of the basic problems comes in - how to "end" the blade.
Secondly, light does not interact with light that I know of, so the "sword fight" scenes from the movies would not occur in reality.
A thought though - what if the light were just a visual indicator of the blade, but the actual "cutting force" were some other phenomenae of a shorter range nature?

Forget lasers, they will only hinder progress. Plasma is where it is at. It can be seen, shaped, and reacts similarly to light sabers in starwars. It's not technically 'light', but it works.

Again, It's called PLASMA. The 'fourth' state of matter.
