I think that Harriet did an excellent job choosing Brandon Sanderson to finish her husband's work. It's true that Mr. Jordan became a victim of his success earlier in the series, trying to keep so many threads going at the same time, never daring to kill more than the occasional character, and perhaps trying too hard to develop additional character stories at the expense of the initial handful of major characters. However I look forward to reading this book, and hopefully the final two books. I think that if what I've read of Brandon Sanderson's other work is indicative of how he'll treat the remainder of Robert Jordan's storyline, then it will be a great read.
Also, the vast majority of services available on OS X Server are open source, which Apple does contribute back. So if you don't like how the Server Admin tool works, you can be a r3@l l33t h4xx0r and edit the config files in vi or emacs and do it yourself.
As for the submitter's original question, there are a number of useful tools available for mass deployments of Macs across a network. Tools like radmind, LanRev, Apple's PackageMaker, InstaDMG, and Casper Suite all have varying degrees of management of machine images, image distribution, etc. Also consider at least downloading the PDFs Apple provides for their built in services to learn the ins and outs of their tools allow you to do and not do. You can even modify existing services to use more recent versions of projects that come with OS X if you're missing something or need to upgrade to a newer version for some reason (although this will likely make you have to freeze your OS version in place, or else future updates will probably overwrite your changes.)
Administration of a network of Macs falls somewhere in between an Active Directory environment and a roll your own Linux/BSD network. The client administration is great, but not as comprehensive as Active Directory. However, you still have the freedom to tinker with the services that come with OS X Server and borrow and add capabilities from open source. There are also many other forums out there that have a much lower troll count than what you'll find here, with many knowledgeable and helpful folks who will actually attempt to address and answer your question.
Because seriously, why go to Slashdot if not for the trolling?
Can someone recommend a piece of software which can help me? Primarily I'm looking for a simple way to list and view the IP addresses used on my network but surely there must be a better solution than using another Excel Spreadsheet?
