Berlin hackathon,we talked with the Kiwix developer and he indicated that making Kiwix ready for localisation at translatewiki.net is one of his priorities.
As it one of those jobs that just does not go away, it is at some stage easier to give it a whirl. The good news is that a first iteration has found its way to translatewiki.
It is now a matter of making sure that new messages and localisations can find its way to and from Kiwix before the translatewiki community can work its magic.
More news when we have it :)
