From AppleBit Technologies:
Seize The ARD allows you to share Apple Remote Desktop preferences with other users, reducing the amount of time configuring a users ARD settings. Preferences such as computers , scripts, scanners, smart lists, and so on can be configured on one machine and shared out to other users running Apple Remote Desktop. This also provides the ability to manage what is available to other users. Great for multiple labs and staff that want to use the same exact settings and views and allows the administrator to centralize the management of the Remote Desktop and what computers are accessible in lists. This is great for environments where you may want to standardize your Remote Desktop settings, for example, Unix Tasks or Group lists. From a single computer you are able to make these changes.
