Sidenote, i wonder if EU requires you keep some information about a user. Ie hypothetically, given some arbitrary P2P setup, you might need to record users that need to be forgotten, any aliases they fall under, etc. Lest you risk publishing said "forgotten" content from another source that is broadcasting. Worse yet if this publication is in a slightly tweaked format that your software doesn't recognize.
