In Mac OS X 10.5-based Open Directory (or higher) and Apple Remote Desktop 3.3 (or higher) you can now add directory services objects as computer lists. Simply open Apple Remote Desktop from a bound computer, click on Scanner and then click on the drop-down list for the type of scanner. Here, select Directory Server and you should start to see your Open Directory objects populating the list, obviating a previous article on populating lists at deployment time.
BTW, if you’re interested in creating computer lists based on Active Directory, start with cn=computer_lists.
Note: Turns out Randy Saeks has also done an article on this topic. Find it here: http://rsaeks.wordpress.com/2009/11/23/using-opendirectory-computer-lists-with-apple-remote-desktop/
