This has been covered several times:
1. the kernel doesn't know who to contact.
2. No one may be logged in
3. the console may not be logged in, but other users are logged in over the net
4. If a daemon recieves the message, who gets the output?
5. root doesn't have access to the X server
6. the person logged in (using X) may not be authorized to answer.
