Are you talking about the client or the server side? The server
should always have the full rpm in case the client doesn't understand
deltas or the deltas don't match.
The client can either work with filesystem data or with the old
rpm.

No, it doesn't do this. Applydeltarpm creates an rpm that is bitwise
identical to the original. That's the beauty of it, you can still
verify the rpm signature and so on.
