Faronics, makers of Deep Freeze Mac, have released User Refresh Mac 1.01.

User Refresh Mac allows administrators to maintain baseline user account
configurations regardless of user activity. The Home directory can be
refreshed on a specified basis, producing consistent user accounts across
an entire enterprise.

Administrators can specify whether the accounts should refresh upon log
out, after a certain amount of time, or on a specified date. User Refresh
Mac allows standard users complete freedom to explore and change their Home
folders without restriction, improving productivity and user experience.
