Great video from Pete Long about VMware View 5 Persona Management. You should also check-out his website at petenetlive.com.
With VMware View 5, VMware introduces View Persona Management. View Persona Management preserves user profiles and dynamically synchronizes them with a remote profile repository. View Persona Management does not require the configuration of Windows roaming profiles, and you can bypass Windows Active Directory in the management of View user profiles. If you already use roaming profiles, Persona Management enhances their functionality.
Persona Management downloads only the files that Windows requires at login, such as user registry files. When the user or application opens other files from the desktop profile folder, these files are copied from the stored user persona to the View desktop. This algorithm provides performance beyond that achieved with Windows roaming profiles.
In addition, View copies recent user profile changes to the desktop profile up to the remote repository every few minutes. The default is every ten minutes, and this time period is configurable.
