Mike Bombich has been making OSX software and instruction guides since there was OSX. In the early days of Macintosh OSX administration, his software was a lifesaver to many a Macintosh administrator. As Apple started to catch up, his software releases started to slow down and (I think?) he got a much deserved job at Apple.
If you haven't used his software, guides or fourms, you may want to familiarize yourself with them:
NetRestore
NetBoot Across Subnets
LoginWindow Manager
Apple Remote Desktop Database Access Manager (ADAM)
Car
