Hi Zack,

You might want to have a look here, there's lots of good stuff:

http://arx.fifthvision.net/bin/view/Arx/LinuxKernel
(Kernel Hackers SCM wish list)

http://arx.fifthvision.net/bin/view/Arx/GccHackers
(Gcc Hackers SCM wish list)

Arx is a fork of Tom Lord's Arch, now in version 1.0pre5.

Regards,

Daniel
