ZFS supports encryption with deduplication, and Dropbox does dedupe accross customers (and why not? It's not a human digging through things).

When different customers use different key to encrypt the data, even if the source is the same, the outcome is different. So it is not feasible to do de-duplication across different customers' data, unless all of them use the same key.
