Are you just saying that you want to write python instead of some shell to
invoke pdal?  Not sure how a python API would help with that.  This is
probably best done with a pipeline (XML) that you could invoke with `pdal
pipeline`, but maybe I'm not understanding.

There are lots of tools out there to do this in various ways.  Hobu Inc.
makes greyhound (not sure on its release status), which can serve a single
file of data based on a query, but we'll have something much fancier and
more efficient shortly.  I still don't understand what kind of an API would
be beneficial for this.  You may have to explain a bit more.
