Yes but we are offering our rbd volumes in another cloud product which can enable them migrate their volumes to openstack when they want.

We have deployed different keys for the different openstack clusters ofcourse and they are using the same cinder/nova/glance pools. The only risk is if a client from one openstack cluster creates a volume and the id that will be generated ends up being the same on an existing volume from the other openstack cluster. But that's like possibility of 1 in 5 billion or something. We took the risk.
