Also I have found several articles that say
"With InfoPath 2010, people can fill out forms online or offline with a native integration of forms in the Microsoft SharePoint Workspace interface. A user can easily take a SharePoint library with InfoPath forms offline in the SharePoint Workspace environment. Information entered in the forms will be automatically synchronized to the SharePoint library once the participant is back online, so people can be productive whether they’re connected to a network or not."
When I try to use Workspace and connect to the Library, I get an error that Workspace will not load the content type.
