It is already in OSGeo4W 32-bit, though apparently not in 64-bit yet [2][3]. On the Mac side, it is already available in the Homebrew package manager [4]. It appears to be BSD 3-Clause licensed. Not entirely sure of its full API, but seems to be an ideal candidate for a Processing provider, yes? While I am not a Lidar guru by any means, it looks like the JSON output from PDAL [5] is also an input for three.js [6], e.g. Qgis2threejs PyQGIS plugin. So that is fairly interesting... may be possible to load in a clipped .las file and visualize your map canvas on it? That would be very cool.
