Maybe It would be a good idea to think up a common format for library authors to 
use, such as the name of the Header to include to register the libraries types 
with Typeof.  Then It would be possible for someone other than the library 
author to add the headers to the relevent libraries .  It might be best to add 
them as subdirectories of the typeof directory, so for example  I would look for 
a "boost/typeof/mpl/vector/register.hpp" header or some such and if not found 
(ideallly!) write it and submit it with some suitable tests for placing in a 
subdirectory of libs/typeof/test/..

In VC7.1 they dont always arrive in the first place ;-)
