Another thought: the recently created communications committee has a special subcommittee for informing local projects on foundation matter. Wikimania CFP could be one of such information which those people are interested in caring for. Or not? (Of course, before they distribute, translation should have been done. But if we find helps, it is great).
I'll bring this up in the next communications committee meeting this week and see if anyone there can help with organising the translations. The meeting is Saturday, 25 March at 23:00 UTC, and people interested in translations are welcome to attend in #wikimedia-cc.
