HAMMER and RAID question

let me start this first by admitting that I know next to nothing about 
designing and implementing file systems.  It is just that I've been 
naively thinking about things.

It is my understanding that code has been added to reblock files during 
production use.  Could this not also be the foundation of RAID-like 
functionality? If blocklists had a notion that a block needs to exist on 
at least two physical volumes, mirroring would already be there.

Or is this too far away from what HAMMER does internally these days?

Thank you,
 Konrad Neuwirth
