Ahh, setup.rb installs directly into CONFIG['datadir'], doesn't it.
Hmmm ... missed that when reviewing setup.
Let's see, the non-gem version of datadir() is ok, because it appends
the project name.
The gem version should return File.join(gem_location, 'data', gem_name).
Then you have to use the extra level in both cases.

If we were to allow access to another package's data, then the package
must be loaded before that access can occur, then we can use whatever
version is loaded.
However, I am inclined to make the rule that access to the package's
data area is off limits to code outside the package ... for all the
reasons you list.

Woah. Do you see a big need for this? I am inclined to not provide
this until I understand the usecase better. If we do disallow access
from outside packages, then this seems like a moot point, correct?

Thanks for the feedback.
