Kent's Hypothosis: Superencrypting different algorithms with unrelated keys can never weaken non-trivial algorithms. Well, it could, just posibly, once in the enrtopy of your adverage algorithim, but then, as you pointed out, you could just use DES as a magic IDEA decoder:-)
You can prove that there is no such interaction if you use two different algorithims on two halfs of a one time pad message, even with the SAME key. Roger.
