This sounds cool but wouldn't it put cinder in the data path if you are
replicating across vendors?

 i would like to Cinder to be able to replicate data between different
backend storages.

 sometimes your DR site does not have the same storage backend as your
primary site, this is common when you rent the DR site.
the usual workaround for this is restore from backup over the DR
storage, which is painful and slow.

 ideally i would have a Fast dedicated storage on primary site and a
bunch of lun(s) attached to a box with iscsi+lvm to provide volumes to
compute nodes.

 if i have storage from the same 'vendor' on both sites that's great!
cinder could offload data replication to vendor's appliance

 i know is a pony what i'm asking for, but i would really make a difference
