> If the only things that changed in the manifest were the updates and manifest number, then there would be no need to retrieve any additional objects, and with rsync I don't believe there would be any other file retrievals. I can't be sure, but I think thge BBN RPSTIR software behaved that way.  Do we get bonus points?

Yes. 

<On behalf of RPSTIR open source team>

RPSTIR doesn’t retrieve any additional objects by using rsync to keep synchronized with repositories.

However, how to deal with those downloaded objects (use/ignore/warn) depends on how we cope with MFT, CRL and local analysis.
