Pdal does have something like lasbuidvrt, it's pdal tindex. I'm working to get Howard and Andrew to support the tindex as a source format.

<div class="gmail_extra">But anyway, speaking just about GRASS GIS, it is surely possible for v.in.lidar (although with significant slow down but trivial implementation). I guess it is possible for r.in.lidar as well. I'm not sure how scalable (in terms of
number of points) it would be when using PDAL. It seems that PDAL can limit it when doing processing but apparently there are ways
