I don't think we ever will pass that phase as we can always use more info. Personally I have no contacts at all to approach to even start getting this info, but by all means contact your friends and ask!

With the latest firmware and XNA studio, you can deploy your own games that have been written using the XNA framework in C#.
I didn't have much time to mess around with it, but standard I/O and filesystem API works. However, it will not let you browse the filesystem using that. Apparently, each game gets 16MB of runtime memory and has a theoretical 2GB max file size. My guess is that there is a small .NET framework on there which seem to be locked pretty tightly. I will try to extract a game from the HDD when I get the chance to see if it has any sort of digital signature.

Has anyone seen the article for cold boot hacking yet? Basically when you shut down your machine data is still in your ram for a small time, these fellas wrote an application that boots off a usb drive or pxe and immediately makes an image of the ram, they also provide a coupe tools for retrieving aes and rsa keys from that image. They tested it to retrieve keys for various hard drive encryption solutions and were successful. I'm curious if you could boot up xp, launch zune, connect the device, and kill the power abruptly after the device connected. Reboot from the usb drive, dump the ram, then search for the key. Here's the site from the fellas that did it, they have video, documentation, and source code. http://citp.princeton.edu/memory/

Yes, we've seen it - No, no-one's bothered doing it.

And I honestly don't think it's necessary. The cold-hack method is for reading the ram on a system that you have physical access to, but not login access. What you are suggesting is doing this to a machine that the zune is connected to, which you already have full login access to, so there are many other ways to read the ram without having to do the cold hack.
