This feels like the Solaris kernel mechanisim for ndd(1), which isn't
a bad thing. The drivers call a function to put variables into the
namespace, with a string name, a cookie, and read/write
callbacks. There are also a standard set of callbacks for reading and
writing unconstrained basic data types (int, char, maybe string).
