Etiquette: how to hug
This video site has a number of how to and self-help videos. For example, the hilarious: how to give a great man-to-man hug video. The videos are informative and often really funny. I could see this site becoming quite popular in the future. They have a niche beyond the usual youtube clone.
So, how about videos on: "how to offer obeisances", "how to ask a question to a senior devotee", "how to enter the temple room", "how to wear a dhoti", "how to eat prasadam", etc.
Such videos would be more accessible than a book and potentially even quicker to produce. All it would take is a video camera, some aspiring devotee actors and a computer with good video editing software (such as iMovie on the Mac).
