If you want to make the BGL serializable, how would you proceed?  
Intrusively, meaning writing the serialize function as a class  
member, or non intrusively ?
You are saying that "One only needs access to the vertices, edges,  
and properties of the graph to serialize it."
However, that doesn't seem easy to get access to these vertices,  
since it would  maybe mean looking at the implementation details for  
a *long* time. Do you think I could write the serialization patches  
in a reasonable amount of time?
If you think so, I could give it a try, with some intial help.

Also, I didn't get a reply to my question about the >> and <<  
operator, and if possible, I'd like to understand that.
