actually, how is this for an idea ...
instead of a file many people would have to update and sync across different 
profiles (huge pita, look at some of the virtual issues for example), what 
about if we extend the IUSE syntax ?  then maintainers of their own ebuilds 
can determine 'default' USE setting on a per-package and even per-version 
basis ...

for example i'll use nano since i maintain it:
IUSE="nls build spell justify debug slang ncurses nomac"
here we will consider 'justify' and 'nomac' ... the defaults from upstream is 
to enable justify and mac conversion support ... however, as the maintainer 
of the ebuild, i've selected disabling justify and enabling mac conversion as 
the defaults, generating the ugly 'nomac' in the process ... in the new 
world, i'd utilize this:
IUSE="nls build spell +justify debug slang ncurses +mac"

now, whenever a user does not have 'justify' or 'mac' in their USE, either in 
the positive (USE=justify) or in the negative (USE=-justify), portage would 
turn around and add justify and mac to USE for this package/version for us

what do you guys think ?
