You can use an existing property name as well, such as vertex_name (or 
vertex_all).  You would then need to change accesses from g[v] to 
get(vertex_name, g, v) (or cache get(vertex_name, g) and use get(that, 
v)).  There is an example at 
http://www.boost.org/doc/libs/1_49_0/libs/graph/example/vertex-name-property.cpp 
(there is also an edge property one at 
http://www.boost.org/doc/libs/1_49_0/libs/graph/example/edge_property.cpp 
using a custom property name).
