An earnest question, myforwik:  For what application is it useful to compute the digests (hashes) of arbitrary small portions of large digital objects? In what context are the hashes of just the first one megabytes of multiple files meaningful and helpful?

If you're doing this for the purpose of file deduplication, you may want to consider other strategies besides hashing just parts of files.
