unfortunately, the answer is no... but I have to say that when I saw the
plotting facilities for communities, I have used that instead.

I guess you need either the edge.betweenness.community() or the
fastgreedy.community() functions. You can pass directed and weighted graph to
those functions.
Anyway, I am forwarding your request to the mailing list, cause you may find
