glad to hear it b16a2smith
I suggest you guys set up an irc room and even a private wiki to generate a community of devs for this endeavor
I guess the community would want to start documenting the layers of the boot process with hard- and software hooks (which may be an adventure in itself) to start looking for any possible exploits, keeping in mind the interactions between the sbf and the bootloader
Of course get up to speed with the milestone exploits and methods like the kexec, and see how much (if any) modifications they need to be applied to the dx
best of luck, we're counting on you!
