Hydrogen peroxide use for CO2 production?

Jamil and Doc recently mentioned that you can add hydrogen peroxide to beer to add carbonation. Doc said it would turn into CO2 and water and leave little, if any, taste. He suggested a capful, if memory serves?

I can see a number of applications. E.g., after moving to secondary, could add some to provide a protective layer of CO2 below oxygen layer introduced in my bucket during the transfer. Especially useful if lagering for an extended time in same.

Anybody ever tried this?
