Well, it IS usefull for some applications. I liked the examples on the
RC5-mailing list. Consider e.g. the recipe for Coca Cola. Even if it takes
you a year or two to decrypt it, that would matter. And there is
other data that should be kept protected for much longer than that.

I guess there will be more options as soon as distributed.net comes around
to make other problems available. The next one will be the OGR (optimal
golomb ruler; a bit math that is in fact used for a few applications). And
after that? We'll see...
