I think this is going to be huge. I place my bet that Sun's Storage market share will increase significantly because of Identity. Unfortunately I'm not a betting man.
"For example, Sun has integrated the identity-management capabilities obtained via its Waveset acquisition with its StorageTek Enterprise Storage Manager software, allowing customers to discover, monitor, report and charge-back users for storage use. The company also is adding encryption to StorageTek storage devices and providing centralized key management for data and tapes via Waveset's technology."
