and fill in the blanks. I last saw a preview of DRM, for example. When i 
send a mail to my college and i don't want him to copy parts of it i can 
secure the mail and functions like copy-past, screen-shot and forward 
don't work anymore. For what i understand this can also be done with PM.

What's the difference in controling rights with PM and DRM? Can i send 
data to a user with some description of the rights what the receiving 
user may do with this data?
