Whence UniData.txt? (was Re: unidata is big)

Theo's comment leads me to a question I've pondered recently:


   Many apps, from independent sources, need to access the Unicode
   character data,

   A lot of these apps aren't overly concerned with the slight overhead of
   parsing the data as needed from Unicode-supplied data files directly.

   Similarly, such apps benefit from being able to easily upgrade to new
   Unicode releases by simply replacing the data files.

   It isn't very user-friendly to for every such app to store their own
   private copy of the character data files when a single shared copy would
   take up less space and be easier to maintain.

It would seem to me that there is some value in establishing either (1) a
standard location where programs can expect to find (or install) a local
copy of the Unicode data files, or (2) a standard way to discover where
such a local copy of these files exist. My preference would be (2), which
would make it easy to configure a network of machines to share a single
copy of the data files. Something as simple as an environment variable
could work if developers were to agree on its name and semantics.

(I understand there may be different mechanisms for different platforms,
but it would be even better if a standard mechanism were cross platform).

So, are there any conventions for this evolving? Or would anyone like to
propose one?
