One option is to use an HTML-based presentation system such as deck.js
The problem of html-based presentation solutions is the lack of authoring tools, but it provides many other advantages.

You can use jquery.i18n to deal with the localisation. Jquery.i18n is a javascript library from the Language Engineering team that allows HTML localisation from the client-side. The messages for different languages can be integrated into translatewiki.net to get them translated.

Julien Dorra and I are starting to work on a template for MediaWiki related presentations. This template will be used for the slides to be shown at FOSDEM (hopefully, if we get a session accepted), and can be used by others as well.

Before making hard choices with technology selections there is a question we want to solve: how to make slides easy to update and localize?

This is the MediaWiki community (including Wikimedia tech), therefore it makes sense to wonder whether a MediaWiki platform wit a Translate extension and/or a plug to https://translatewiki.net/ could help here...

But even if that backend would work, how to go from strings translated and updated via wiki to a final and nice-looking PDF or HTML based presentation?

Your ideas welcome at

(short URL in case it breaks: http://bit.ly/TaWeQK )

or here, of course.

If you want to get involved in the production of this template and the slides, in that URL you can find the other topics we are discussing right now.
