Hi Adam,

I don't know if you are actually particulary interested into the steps that 
will _not_ involve copying, or if you are simply interested into getting the 
graph resulting from the filtering into the original graph-type.
In case you don't care about the copying, you can simply use copy_graph() 
(defined in boost/graph/copy.hpp).
Although I could imagine that avoiding copying might be quite crucial for your 
applications.

Best,

Cedric
