That gets into more of ciaran's HOME installation target feature.
Current form for global prefix offset is
DOMAIN="root offset" , with offset == prefix offset.

If an ebuild doesn't have DOMAIN="offset", and you're doing a prefix 
offset, it's unusable.  No question of "can I use a dep from another 
prefix", with prefix offset you're doing the deps full in an offset.

As stated earlier in this mess of a thread, HOME crap is being left to 
those who want it, it'll be implemented by those who want it after 
global prefix is ironed out (if it is accepted also).
