Binary packages are useful, but you can't consider them a true fix to our
problem. In 2011, having to do all this manual work just to keep a system
running seems wrong. Especially when there are other solutions that would allow
you to avoid all that. 

Implementing something like my proposal would save a lot of systems with
minimal cost and make Gentoo more reliable in the public (and corporate) eye.

IMHO, waiting for a year to push a serious change is unacceptable. We're a
bleeding edge meta-distro, I'm sure we can do better ;)
