I am planning a SharePoint 2010 solution with an intranet / extranet and internet site.
The intranet and extranet will probably use different authentication methods. The internet site will probably be in a different domain (DMZ domain)
How can I publish an article on one site, and then have it published to the other sites? Is there a way to do this in SharePoint, or should I for example use Biztalk between the sites?
