From what I've seen while studying in an academic research lab: The tools student researchers were designing (commonly in Jython at my school, btw) integrated multiple networks at once with surprising fluency. It was often a dopamine-stimulating part of demos to say something such as, "See, this is the extent of the phone number graph, and now we add the email data <click> and now we add facebook data <click> and now resumes <click> and now mailing lists <click> and shopping records!" Also, they use discrimination functions to weed out nodes with heavy use, like a restaurant take out number. Typically, they can histogram # of connections and use central moments such as kurtosis to determine if a particular node has too many connections.
