I doubt about Paul reading this thread. Point cloud implementation is 
independant of 3D, and even of PostGIS for now. It is also really new.

As for now, 3D in postgis only exists in a specific branch on git. It is not 
incorporated into postgis trunk. That will be subject to discussion at the 
next Boston code sprint in march.
As for QGIS support, it is highly experimental. We managed to get the globe 
plugin read 3D objects, but it required modification in the OsgEarth toolkit 
and the globe plugin itself. Patches have been sent upstream, but do not 
expect to find it working in any available binary qgis distribution.
And it needs a lot of work to get something really useful.

You will find some more infos and videos here :

We are working hard on the subject, and no doubt at some point Paul's work on 
point cloud and 3D stuff will meet :)
