An online fanclub site offers free video clip downloads for its members.

What we did is a separate application from the fanclub site that serves this video downloads securely.

The video clips, whose each size could be up to hundreds of MB, is uploaded via the admin area using SWFUpload, so that the uploader can see upload progress bar.

Members can then download these video clips. Using BitGravity CDN service, we make sure the download links expire within a short time frame and with a secret hash. This is so that unauthorized users cannot download the video clips.
