[wp-hackers] How to download multiple language packs via the API

[Nikola Nikolov]

Is it possible yet(or is it coming in 3.9) to automatically download
language files for WP, plugins, themes?

If so, is it possible via filters/action hooks to ask WordPress to download
the language files for multiple languages, instead of just what the
currently active language is?

I'm asking this, because I resumed work on my multilingual plugin. In it
I've used a modified piece of code from qTranslate that would look for
translation files and download them from the WordPress.org repo.
Since I don't really like how it's written, and because of the fact that
this is/will be in core anyway, I don't see why to reinvent the wheel.
