I'll take a look at it and see about hacking up a prototype :-).

The general consensus that was reached on the rough design of it was:
/etc/portage/package.env:
ebuild-atom file 

where ebuild-atom is a complete version atom per ebuild(5) and file is
one or more space-seperated names of files found in
/etc/portage/package.env.d/ that get used after /etc/portage/bashrc.
