Your mac expert is certainly not one, and I am sorry for you. When I was managing hundreds of macs, I used radmind, and I could have easily scaled it to tens of thousands. (given appropriate funding)
'She refuses to use MS Entourage' She is actually correct there, but only because Entourage has this nasty habit on OSX of trashing its own database. *shakes fist*. We pushed people to mail because we did not have an exchange server, and we were sick of supporting it.
Radmind is definitely its own thing, and it would scare most people, as it asks a lot of the user. For small (up to 100-200 maybe) computers, apple remote desktop and a task server would work fairly well. It is a lot closer to SMS, and it is all graphical.
Apple's group policy like thing in open directory is rather good, but it doesn't do all the things that group policy does. It also does a lot of stuff that group policy cannot, so I really don't know if one could be called better.
I used to run a network with hundreds of apples with radmind. We installed the initial images with NetRestore (multicast for the larger influxes), and upon reboot, the computers would download their radmind certificate from LDAP and install all of the software that it needed.
It takes more up front time to set up and configure radmind, but it works wonderfully for almost anything you want to do.
One of my good friends is a food scientist. She has her doctorate in it, and works in the field. She cooks almost all of her own food, and will rarely eat processed food, and never fast food.
It also let the US have sole control over Japan and not have to split it with the USSR. I don't think the nerds were thinking about that though, so I don't fault them.
Nerds are the ones that know how to use game theory, and I could definitely see that ending wars much faster than soldiers.
AD and GP often make no sense in the *nix world, as their are often much, much easier ways to do things.
Just because people get comfortable with a stupid way of doing things doesn't mean that Linux should copy it. Group Policy seems to be the current holy grail of MS System Administration, which seems slightly ridiculous, as much of it is either solutions looking for problems, or problems that were solved on *nix 10 years prior. But, without any specific things being requested, or details of the setup, it's rather hard to suggest pertinent things. It's linux, there are 5 - 500 different ways of doing things, but you only need to learn 1. The good news is that the 1 way will actually do what you want.
*nix is not about having huge systems that do everything, it is about having small tools that talk to each other in intelligent ways, and can be easily strung together to get almost any job done. The sysadmin tools are mostly like that too.
10 Gbps is already normal in server rooms. OC-768 is in the wild at around 40 Gbs. 100 Gbs is definitely around in labs, but I'm not sure if any of it is retail yet.
SATA doesn't have to be very fast, because a single hard drive isn't very fast.
Partition it into two drives. Put the home directories on the second drive. Manage a build with radmind. Once a year, people come in and get the first partition wiped to get a new build. If you need more help, email me, jdobbie@gmail.com. (Yup, I've done stuff like this before)
CentOS and other redhat based distros have their place, but if you don't have the infrastructure in place, they are a bitch to maintain. Go for Debian or Ubuntu. Ubuntu even has a LAMP option in its install. Write some cron scripts to apt-get update; apt-get upgrade and you are already ahead of 60% of the internet.
As for performance, get a better server. Until you start running into some fairly hairy issues, new hardware is the cheaper way to go.
Let's assume that everything is stored in a "Big Huge File of Death". Touching the BHFOD is pretty scary, because it was probably not structured well, is binary, and the only documentation for it is the COBOL code. Hacking together some perl code to unpack it and change everyone's salaries then looks a bit scarier. Let's assume that there is no batch change in the system, and there is no way to give people their old salaries back. With the current data entry personnel, it'd be quicker to set everyone to minimum wage, because they'd just go person by person. Setting it back would be harder, because you have to enter different numbers, and there will probably in inflationary raises or other fun things to make it harder.
Or, one could hire a COBOL programmer to add a batch update function that has the ability to reset people to their old salaries. But... it's hard to do that when you can only pay them minimum wage.
Apple has historically not given a fuck about pleasing everyone. There are people who are very happy to pay the cost, and there are enough of them to support the company. If they don't make a product that you want to buy, it doesn't mean that their products suck, it means that you shouldn't buy one.
Info and man pages are incredibly useful, and your students will need to learn how to read their at some point. Beyond that, google is the resource for system administrators these days. Philosophy is found elsewhere, but the nuts and bolts of configuration are usually found on the software's website.
Any book you get will be outdated and you will be making poor students spend $50 that they don't have.
Did you try unshielded lamp cord? I doubt that the kitchen is a very good room acoustically, and the speakers probably aren't great. A 50" run might not be too much of a problem.

10Gbps is cheap enough that even third tier colleges are thinking about using it for their trunks and inter-rack links.
Infiniband is solving a way different problem.
Let 1000 people drink?

Dude, the eco lobby has been pro nuclear for the last decade. If you want an enemy, look at who seems to be spending a lot of money on PR.

But you could always LARP. People seem to like that for some ungodly reason.
Why AMANDA over bacula? The lack of native clients makes me scared of AMANDA.

Towards the end he talks about it.
Fuck that.
'Sysadmin work is the new "tech ghetto," we hear.'
That makes me hope that their admins go BOFH on them.
YAML and Ruby play well together. (or perl, or Python)
CSV has a perl DBD driver for it.

Why go with Office2008? It isn't the friendliest with network homes and it is dog slow. Neooffice or OO 3 might work far better for you.
If you are going to do a long run, and sound quality is important, you should use something balanced.
