My experience with "hand raising" interfaces has been that it takes clicks, when it should be a first-class operation as easy as speaking itself. Indicators for speaking, too, are insufficient. I think every video chat app has that, but what they don't have is "I am _about_ to speak", like "I would like to jump in now"; An interface equivalent to that thing people do with their body language to signal they're about to speak (they raise their head, open their mouth, perhaps lean in a bit). Not as extreme as "raising my hand".
