Video on the Net is progressing leaps and bounds. Most of it is personal videos. Business videos are not so hip yet. They are confined to Q&A for a while. I think we are unlikely to see business related video documentaries on Internet for a while. And when they arrive they will mostly be in English. I think there is a huge market for dubbing internet videos, especially the business videos.

If there is an online forum or some sort of an exchange where the dubbing professionals and content producers can interact and trade, you could have a business there. Content providers could then offer language preference off their TV client for each video.
