I'm not sure about the mentioned services, but JungleDisk does encryption
and does "duplicate elimination" (allegedly on blocks of a file, not just on
the whole file). They're pretty tight-lipped about their process, but from
what I've been able to determine, it looks like they do the "duplicate
elimination" prior to (locally) encrypting.
