Well that's all nice, but that would also need to be compute-efficient for it to be worthwhile and near-real-time dedupe of memory pages would be a REALLY tough challenge.

Pretty straightforward for disk blocks. Many VM disks are already de-duped, either through snapshopping or through copy on write host filesystems.

The host block cache will end up deduplicating it automatically because all the 'copies' lead back to the same block on disk.
