Alot of the text output is integrated tightly into the code so there would be a fair bit of work providing translation options, although not improbable that it could actually be done.
We've been hunting around for some 'quick win' ideas like integrating automatic translation via the google api into a plugin. This involves walking the text nodes, and it's something that I'd have to look into further.
For anyone else hunting, using jQuery to extract text nodes is done with this snippet:
Or it looks like google has a package that does the translation thing already as a jQuery plugin: http://code.google.com/p/jquery-translate/
Obviously having google translate something as opposed to an actual translation isn't ideal, but since it could be implemented fairly easily through a plugin maybe it will be a short term solution?
