At Nexenta we've been working on an alternate versioning proposal that incorporates distributed deduplication. An Etherpad description is available at http://etherpad.openstack.org/P9MMYSWE6U This would be targeted for the F or perhaps even G release. Read the etherpad, there is a fair amount involved. John's proposal is less ambitious, but at the cost of not dealing with certain issues like large object support and Providing for uniform distribution of storage without requiring migration of content when it becomes an old version.
