We make heavy use of the boost::units library, including our own 
additions to wrap up user unit conversions, and developed a type 
description library that can be used to implement runtime reflection and 
MPL generated edit controls in a GUI.

The MPL part is just one aspect of the overall system though.  You need 
more techniques, only some talked about in the MPL book.  However, if 
you learn about how some of the Boost libraries are made you can pick 
these techniques up.  A couple in particular are boost::any and 
boost::function<>.
