Comment (by yawning):

 Not interesting.

 Despite what guidelines say, the best known attacks against 3DES are
 computationally infeasable.

 The best known attack against 3DES is computationally infeasible
 (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.119.1761&rep=rep1&type=pdf).
 Anything that could break 3DES could break 128 bit AES as well, because
 the only likely feasible break is a quantum computer.

 (Landauer's principle doesn't go away just because you have lots of
 money.)
