Hm.

I think I'm arguing for a documented registration interface that looks like 
this:

namespace boost
{

namespace type_of
{

template< class V, class T > struct encode_type;

template<> struct encode_type< whatever-is-required >
{
    whatever-is-required;
};

} // namespace type_of

} // namespace boost

I've no idea how practical is that.
