I once made a cooling system for a small server room that used tap water.
I don't want to recommend this though, because running significant amounts of water through a server room is generally a bad idea:)
I got some aluminium sheet bent to a duct shape, so that it ran from about 20 cm from the ceiling to about 50 cm above the floor. Inside the duct i placed several of the larger type radiators that are used when cooling overclocked computers with water.
At the end of the duct I placed 3 20mm fans that would pull air through from the ceiling down through the radiators and out at the bottom.
A thermostat stopped the fans and waterflow (magnetic valve) when the temperature was low enough.
Radiators were connected in serial, so that the coolest water was closest to the fans.
This server room was inside an industrial area where water was abundant and free of charge, so water came right from the pipes, ran through the radiators in the duct, and then right down the drain after cooling the air.
CONS: Not a very efficient setup, requires some DIY work, and you risk flooding your server room.
PROS: In this case it was cheap, and we had no accidents;)
Some of my work is to develop basic services for ISP's. This includes systems that manage the sale and delivery of, say, an ADSL subscription. The system can generate your PPPoE username, and provide it preprogrammed into your modem. Our services include the authentication services that are later used to decide wether you can have access to your service or not. The ISP can access your account, and know what IP address you've had at any point in time. The search can also be reversed, to find out who had a specific IP address at a given point in time.
I have to say, these data are not available to the general public, so in that sense your IP address doesn't say much about your person. The problem arises if the police are given access these data more and more without the need for court orders and such, it becomes easier and easier for them to "interpret" what they find in any direction they'd like.
Let's say my computer got hijacked, and was used in a computer break-in. I get prosecuted for this, and my logs show I've read a lot about computer vulnerabilities. Doesn't look good, does it? Even though the reason for the reading up on vulnerabilities is tied to my work, it becomes pretty easy to paint a completely different picture.
I haven't read TFA, but I at least partially agree that IP addresses are personal data. If you could combine all the logs that exist from your movements online, they have the potential to say quite a lot more about your personal behavior than most people would be comfortable with.
I am under the impression that VMWare has or is in the process of releasing a system where the VMs run on servers, and you can use think clients to view the vm. This approach gives you all the the benefits of snapshots and other good VM stuff, possibly audio, and also the very controlled hardware enviroment you seem to be looking for.
> A microwave device can be defeated by the good old tinfoil hat - by which I mean wallpapering in foil or otherwise turning the room into a faraday cage.
Make sure you fasten it properly, then:-) If the tinfoil is loose, it too will vibrate, increasing the effect described. Tin foil reflects microwaves better than fabric.

...and the dinosaurs became extinct approximately 65 million years ago? Something tells me it's time for the tinfoil hat again...
