Hi Andreas, I think this was basically the result of the sometimes special level of paranoia that went into the TC design. I would say there really is no reason to mistrust AES at this time. Also remember AES gets hardware accelelration on most platforms these days, but Serpent (for example) does not. That makes a rather large difference. But if you think you really need this, you can layer LUKS or put plain dm-crypt volumes inside each other and inside LUKS containers. May have bad performance impact beyond the additional encryption though.
