After all the fun with the AACS last week, it turns out that anyone can get their own 128bit number which can then be defended using the DCMA :) This is done by generating a Haiku which is then copyrighted. The Haiku generated for me was as follows:
The haiku is copyright 2007 by Edward W. Felten:
We own integers,
Says AACS LA.
You can own one too.
Here is your very own 128-bit integer, which we hereby deed to you:
02 BA D1 6C B8 DD 0F B8 30 76 41 7A 08 53 0D D1
Not sure how well this would stand up in court, but it's interesting none the less.
