Thanks for your in-depth reply. I will probably circumvent the default WordPress comment system and fully use Disqus. I sent an email to the Disqus team, however I’ve got a feeling that I’ll need to purchase their professional add-on package to get their full support on the implementation. From the information outlined in the OP article, I’d say that this was the route that the Telegraph.co.uk took as well in order to get your three way system up and running?
