I have been using the plugin for a day or two, and it generally works. I have some issues only because of my custom settings via custom post types and taxonomies. It is smart enough to pick up on custom post types, but just comes a little short when getting custom taxonomies. Still, the plugin has given me the least headache for the functionality that is made so hard to accomplish by the different networks.
I rate this plugin and developer, A+++++ would download again :)
