I fully agree on this ;).
My point is that we should not exclude a variation of an algorithm just
because he is "too" good ;).
The only big disadvantage I saw with AES256 is from time to time
iPhone VPN for instance doesn't support AES256 (at least it was the case on
Java JDK doesn't permit to cipher with AES256 except on Mac OS X (at least
when Apple was packaging the JRE).
