If a duplex contract is not workable in your environment, you will have to resort to polling. Your initial method could return an identifier (a GUID perhaps) and then you could make subsequent calls to another method to check the progress, and pass in the identifier.
This will obviously require you to store the progress information somewhere (like a session or a database), which is not great.
