The current mechanism is to have periodic full baseline manifests, and then have deltas against those baselines in between. Hence, no more than two artifacts ever need to be decoded in order to access a manifest - the baseline and its delta. Are you proposing to have deltas of deltas, so that a potentially large number of artifacts need to be decoded in order to reconstruct the complete manifest? I don't understand how that would help. Can you provide more explanation? -- D.
