that's what LIveNation is doing - with lots of help from Ortsbo, I would imagine:
"David also talked at length about their new service, the Social Hub. This is the product that I think has the most potential, and from what I have already seen is a great way for anyone with a social presence to connect their audience together across language barriers. The first example of the Social Hub was launched by the band Kiss earlier this month as they kicked off The Tour. Lucatch mentioned a deal with Live Nation to aggregate and translate social media for more tours and bands but could not yet announce any names."
