I did get to email mshaver yesterday asking access for a forum server. The reply I got was they want to make sure that Drupal (MeeGo.com's CMS) and vBulletin would work well together first. He also said that the Technical Steering Group (TSG) needs "to review and bless any implementation" that needs to be created.
It looks like the SSO is the big blocker here. Hopefully Intel has the resources to help code something to bridge Drupal, vBulletin, and other upcoming systems.
