When multiple users upload the same file on cloud storage services like Live Mesh and Dropbox only copy of the file exists, and each user is given a link to the file.
When a DMCA notice is received for a file shared by a user, the common practise is to remove that users link, but leave the actual file (and other users' links to that same file) intact.Now here comes the crazy part!
As a part of the case against Megaupload it is alleged they didn't apply a comprehensive take-down method when notified of a copyright infringement via a DMCA take-down notice.
Essentially the DOJ is saying to comply with a DMCA take-down notice a cloud storage service provider must delete the actual file
and therefore break all user links to file.
Megaupload (and I assume other cloud storage services) applied this method to child pornography. e.g. once a child pornography image was reported its file hash was saved in a black list, if anyone else tried to upload the same file it was rejected.
I'm not sure if Microsoft (or others) are applying the same method to copyrighted files, but depending on the DOJ against Megaupload at some point soon all cloud storage service providers may be compelled to implement it.
