Hey Clint,

yeah that's correct but you will have many old applications like 
Wordpress or Magento they can't use out of the box an object store. You 
have customers with applications they'll not customize the application 
only to host that stuff.

This feature will have Havanna release but it's more then 6 months if we 
can "use" this as stable.
