I'm aware that that SharePoint 2010 includes a feature for assigning document IDs to files within SharePoint site collections:
What I'm wondering is if SharePoint also applies document IDs to file share content sources that have been added as part of the SharePoint search crawl. In SharePoint 2007 we have users that create links pointing to files on a network file share. Occasionally, a file gets renamed or moved and ultimately breaks the SharePoint link. Do SharePoint 2010 document IDs apply in this scenario and provide persistent links in SharePoint for file shares?
