Details on Ubuntu's UEFI secure boot plan

I use Linux based netboot solutions to install images and I often do this remotely. In particular, I'm currently using FOG to install XP and Win7 images and I've triggered this remotely more than once. As an added wrinkle, I also use Linux to remotely image both OS X and Windows to Intel Macs.

I absolutely have to have machines able to boot in Linux, install the OS images required, then boot into the non-Linux OS that the end user is going to use. Vendor centric Secureboot could really mess me up.

At a minimum, I need to be able to add keys to the BIOS on these machines that allow both my imaging infrastructure and Windows to boot. We are phasing the Macs out by attrition for other reasons.
