Debate? It's the Justice Department that's had a brainfart, that's 
what's happened. Apparently it's meant to ease criminal investigations 
involving electronic communication (read: terror investigations). But 
it's totally meaningless, since public terminals (like in an Internet 
Cafe) are exempt from the law.

You can read the entire thing in Danish here:

The relevant part is Section 5, which says (losely translated):

ยง 5. A provider of electronic communication nets or services for end 
users must register the following information about an internet 
session's initiating and terminating package:

1. Originating Internet Protocol address
2. Recipient Internet Protocol address
3. Transport protocol
4. Originating port number
5. Recipient port number
6. Time of start and end of communication.

Well, value, schmalue. But it's the law...
