Projects like Sequoyah have started using Google Translate for some of their
i18n efforts. Unless Babel is no longer active or focussed entirely on the
Translation Server, some of those efforts look very good and constructive.
Not to mention Google's own UI and Message translator inherited with
WindowBuilder, but that's another story.
Since many Eclipse projects are now also mirrored on Github, this Github representation of a Translation Service Provider could be of interest for Babel: https://github.com/myGengo
