It's interesting you mention LiDAR, but I would like to stick to point
cloud, or point data set if you will.

I was approaching this issue and particularly OGR as a solution for data
conversion and reduction. I am quite fond of the functionality OGRLayer
makes possible in a transparent way, such as reprojection and spatial
querying.

But I will have to agree this functionality may already exist elsewhere and
as such there might reduced interest in offering it within the OGR API that
I am so fond of. Fair enough.

Rui
