Offline data persistence?

Hi,
Will WPF/E have a mechanism to save data locally for off-line usage similar to Flash/Flex's Shared Objects? Also, will there be a way to take a local WPF/E applet and somehow assign it to an Internet domain so that it can be truly used in an off-line fashion (think Adobe's upcoming Apollo) and then sync up the data later when an Internet connection is restored?
Thanks!
