Live Demo CD of Microkernel-Based TUD:OS Released 103
Norman Feske writes "The OS Group of Technische Universität Dresden (TUD:OS) has released a live demo CD of their custom operating system project. TUD:OS is a microkernel-based operating system targeted at secure and real-time systems. Some highlights of the demo CD include a new approach for securing graphical user interfaces called Nitpicker, multiple L4Linux kernels running at the same time on top of a custom L4 microkernel, a survey on the reuse of device drivers on the TUD:OS platform, native Qt-applications, the DOpE windowing system, games, and a lot more. More information is available at the demo CD website demo.tudos.org. And yes, there are screenshots, too!"

The system architecture looks fine and dandy (L4 is a pretty good base microkernel), and I love the capability to make this system perform 9 different scenarios, including running L4Linux for when they lack their own software.

Aside from this, it's true that having a hardware safe for cryptographic private keys (the fritz chip) is sound from a security perspective (while takign control of what the chip will or will not sign away from the user is bad).
The reason I was comparing this TUD OS with TC is that the intel and AMD TC platforms both implement memory curtaining to isolate programs from one another, which this project seems to do quite nicely with a software-only solution.
And let me rebuke this OT but blatantly false line: It is relevant to anyone who has any interest to legally buying content which is sold with DRM restrictions. Even in the best of worlds, where the content sellers play nice, DRM stops me from playing something I bought from company X on anything but the players approved by company X. (iTunes audio files on anything but an iPod?). And if company X goes out of buisness or just decides not to support that format anymore you may be unable to play those files ever again.
And in the real world, companies which can effectively write a different copyright law for each piece of content will use this to their advantage and to the user's disadvantage: to milk more money by selling the same stuff multiple times, and to hinder interoperability in anti-competitive ways.

Erm, if your computer is properly secured you will never know that Sony's DRM is on the disc, because your computer won't be looking for files on an audio CD.

Exactly (I think ?). If it doesn't look for files, doesn't auto-run them etc. (ie. it is properly secured), then no files from the CD can possibly be executed. So... the DRM has no effect on my computer.

It runs in qemu just fine. It's even described on their site how to do it.
And you can always burn it onto a physical CD-Rom, and boot it up in a physical machine.
several of the demos didn't supply a "reboot" option so I had to exit the whole thing, delete the vmware files, except the vmx, and refire wmplayer so I could get the tudos menu again. It's been years since I've run a Linux distro that was this buggy or hard to use.
It's a CD-based demo, so your vmware files won't have "state" in them anyways. Just kill your vmware, and restart it, without wiping any files.
