My reading of the DMCA (and IANAL) is that any system that you use is
deemed effective if it works in normal circumstances to protect your
content.  As such, I believe that the use of rot-13 is a better
engineering choice than the use of AES.  rot-13 is smaller, faster,
less buggy and equally effective, given that the key is stored locally 
with the content.
