I use it for re-imaging a system all the time. A manual Ghosting process but you can map to any server on your network and re-Ghost a system quite easily.

Have not attempted any RIS stuff with it though as rarely do you have the opportunity to remotely re-image without first storing the current data from a system.

Altiris (imho) is the most advanced vendor out there anywhere to handle all types of imaging and automation of a network of systems.
