Right; and part of what I'm hoping to do is add support for xdg to Loki...

Yep.  The whole problem is when you say 'try $XDG_DATA_DIRS', what
exactly does that mean?  I'm trying to write a single .desktop file;
do I write it to every directory listed in $XDG_DATA_DIRS?  Do I write
it just to the first directory, or do I (my personal favorite) write
it to the first writable directory in the list?

Note that I'm actually not waiting on this; my implementation is done
and works.  My concern is that I want to improve the specification so
that others can find it simpler to do this in the future.

Cheers,
