At some point Microsoft tried to sell some automatic DRM system based on SharePoint to some company that I worked for.
The sales pitch was that they could upload documents to SharePoint and when people downloaded the documents SharePoint would automatically apply DRM so the documents could only be opened by that person on authorised machines for a specified number of days.
Well, it turned out depending on how you logged in (using the same account, just different login forms) on the SharePoint server it would either give you the files with DRM applied - or the completely unrestricted files.
We got some senior Microsoft consultant working directly for Microsoft to look at it but in the end they were just as confused as us.
