Hi Momso,

>>>- Devide curve by Length / by number of segments

Just use the "Array" along curve. That can be by lengh/ number of segments. Splitting etc can then be done if required.

>>>Can I add one more function? It is 'Curve from 2 Views'. I think it is very good and useful function for modeling.

Currently, you can perform boolean Isect which can give the same result. The curves are auto projected by extrude to give intersecting surfaces, these are split, so the intersecting edge can be copied/pasted. It is then just a need to delete the un-needed surfaces.
