The main thing if you just want that syntax is that you would need to have 
operator[] in your graph type.  Getting full bundled property support 
would including allowing syntax such as get(&vertex_prop::color, G) and 
such; those are somewhat more difficult.  If you do not need full 
compatibility with all of the bundled property features, though, 
operator[] is enough to implement.
