DOORS and Team Foundation Server Integration

I have a customer using DOORS 9.2 and TFS 2008 and the Integration. This customer is wondering if there is a way to automate the Synchronization. Maybe using a script on the Microsoft side. Has anyone built such a solution and would be willing to share what they did to automate/schedule the syncing?
