Hi Keith,
Just a short remark, more to follow.

This does not work, it never did and it never will. First rule of
iterators: Don't derive from an iterator.
The reason is that the operator return types get messed up. BTW this is
the reason why ia uses the CRT pattern.
const_iterator x;
const_iterator y = ++x; // Uuups does not compile
++x returns a boost_const_iterator!
