This looks fine in general.
I've needed something like it so I'm intereseted on seeing this on boost.

Some issues:

Why 'index' instead of 'key'? Associative containers use the term key
instead of index,
since index is typically related with random access instead of look up

(2) I would explore a friendlier interface. For instance:

(2.1) key uniqueness could be specified along with the key itself
        and not with a separate template parameter.

(2.2) keys could be tagged so that 'get' could be parametrized by
        key tag instead of number.

(3) This is a showstopper for me: The key mutating operations should
use a higher level interface which protects clustering and ordering
With the current interface, if I understood correctly, I could forget to
call update() which would break such invariants.
A better setup would be to use something along the lines of
the 'modifiers' used by the CGAL Library.
