I haven't looked at it yet. Can this code be integrated in the next Loop-AES cipher package?

I´d like to use two loops on one partition and use at least two ciphers to gain better security. Size of devices in my case is 200GB (my complete old WD drive) and large portions of the newer 320GB drive. With perpendicular recording drive space will increase considerably in the next months. Do you see a limit where AES or other ciphers can no longer cope with that? With a passthru kernel patch (http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/old/) I managed to turn on and off my old 200GB serial ata drive. The command is "hdparm -y /dev/sdb". This way you easily get more encrypted storage without mounting dozens of dvd images and all that crap. Anyway, 64bit implementations of any cipher are always welcome.
