Chris,

I made a pull request that implements just about everything with the latest PDAL codebase. It should work with any PDAL-readable, not just LAS files. Anything that you can pass into PDAL as a filename (file.las, file.xml, file.sqlite, etc) should be inferred and read. 

I was unable to get things to fully compile on OSX due to some interesting and probably horrible OSX STL bug, but I was able to get past the PDAL parts anyway.

Hope this helps,

Howard
