Would it be worthwhile to put your example (or a variant of it) into BGL's 
example directory?  To do that, you would need to license it under the 
Boost license, and I might change the formatting and/or naming conventions 
to fit BGL ones.  Also, why are you using forward_iterator_helper rather 
than iterator_facade?
