Octane requires light to be emitted from a physical object - so a Directional Light is not really applicable (unless you use an Area Light a long, long, long way away). Similarly, Spot Lights are non-trivial, and would require actual geometry to control the softness, etc, and IMO it would be easier to simply use an IES file. A point light is possible, done by creating a very small sphere.I agree with you. We need absolutely more type of lights in Rhino plugin. For me this is one of the most important feature that I would love to see in the next release.
