Yep, windows for the win. I think/hope there are other ways that open-e is investigating resharing snapshot luns. For example, you could have a snap shot be mounted by the OS read only and then shared via some NAS protocol.

Another very dirty method would be to have another linux host with NTFS support and iscsi initiator and mount snapshots locally then export the mountpoints with some NAS protocol or have a veritas agent installed on it.
