I'm using MSVC 2010 for the experiment, if that matters... Using 
adobe::bidirectional_iter gives me

adobe\any_iterator.hpp(154): error C2675: unary '--' : 
'boost::multi_index::detail::hashed_index_iterator<Node,BucketArray>' 
does not define this operator or a conversion to a type acceptable to 
the predefined operator

Using adobe::iter gives me:

adobe\any_iterator.hpp(63): error C2039: 'interface_ref' : is not a 
member of 'adobe::poly_iterator_instance<V,R,D>::type<I>'

So I think I'm stuck here... I'm trying to use this with a hashed_unique 
index with a composite_key; the item in the container is a shared_ptr. 
The (corrected) example from their docs that uses std::vector seems to 
compile.

It could be that poly_iterator_instance is missing some 'using', I 
haven't looked into this much yet.

Thank you,
Filip
