They have. See second post here

I wonder if a GPU could be used for AES?
Re: eCryptfs vs LUKS
LUKS is block device encryption (e.g. /dev/sda1)
ecryptfs is file level encryption (e.g. /home/user/Private/). You mount a folder, and every file created in that folder will be encrypted individually. If you umount the ecryptfs folder, you will still see the files, but the contents will be garbled.
There are several advantages to this approach, but the main one is that the home directory for each user can be encrypted with a different key.
With LUKS, it is only possible to encrypt the home partition, or with more work, create an encrypted partition for each user (with fixed size, less flexibility).
AFAIK, ecryptfs is available on Fedora as well.
It really didn't mention game performance but of course that will be largely unaffected, especially if your games are installed to /opt or other places outside your home dir. Wine games might suffer some though depending on how I/O intensive they are.
Yes it is possible.

Aso if you own the book GPU Gems 3 there is a dedicated chapter to this subject.

I'd like to see how encryption runs on SCSI. I'm tired of the inconsistent performance with desktop controllers.
Encryption would be really cool, but getting locked out of your data is unacceptable.
That would apply to a very small amount of the community. If your running scsi's chances are your running servers in a corporate environment and you should have alot more security measures in place then just encrypting the drive.
