sorry for the late response - I'm thinking about re-implementing
this along the lines that you are talking about. Especially in light
of your new configuration options. The reason(probably short sighted)
for the previous approach was that the creation step was already being
handled in our venet driver(but it doesn't have to be).

Thanks for the suggestion.
