I kinda thought up a system like this long ago, but it was more in line with 
node-based profiles.  And wou;d've required gutting the current profile code in 
portage entirely.  The idea being that, you construct the profile up in nodes 
from the top level (much like one does their PATH variable), and the profiles 
would be re-arranged into things like arch/, libc/, kernel/, etc..  In a way, I 
re-organized mips' 2007.1-dev profiles to quasi reflect how we'd look in such a 
layout.

But I like this idea -- it goes halfway towards nodes to some extent (at least 
lines things up for nodes or some other implementation that maybe treats parents 
better).

antarus even had a small draft document up on it that's better in detail:
http://dev.gentoo.org/~antarus/essays/mixin-profiles.txt
(later on, it was decided that there would have to be a pre-defined order for 
the first four nodes: base:arch:kernel:userland, and these first four nodes 
could not repeat.  Everything thereon after was swappable and allowed to be 
placed in any order, such as base:mips:linux:glibc:ip30:o32 (where o32/ip30 can 
be swapped around))

But I definitely see this as a 2008.0 thing at the earliest.  I also see no 
problem with mips joining in on the fun to play with things either!
