Actually, look at the loop device for linux, and
ftp://csclub.uwaterloo.ca/pub/linux-stego/index.html
for the encryption and stego extensions. You can add DES or IDEA over a
file, partition, or device - every block is encrypted, and you can impose
any desired filesystem you have a mkXfs for. Note that linux has to come
up to the point where you can set up the password, but I think it can be
done with the initial ramdisk with only a little effort. It is actually
quite transparent except for the CPU time involved in the en/decryption.
