I would say - watch this space.
It's going to be a very RWD year at Coffeecup and the move away from Flash with forms (and now responsive forms) may well mean that other popular flash based apps are going to receive a make-over.
While I'm no fan of Apple and their attempts to control the user experience so tightly, it's a fact of life that iPhones, iPads and iPods are everywhere and there seems to be no chance that Apple will allow Adobe Flash to run on their devices any time soon.
Given that the world is also full of Android smart phones and tablets too, as well as devices running Windows mobile and other platforms that do run flash, you could make a video part of your RWD approach and have it run for smaller screen sizes.
But the whole idea of rwd is to take advantage of the fact that you can change the layout to suit the device viewing your site, so for smaller devices, use styles that keep it simple with easy navigation and smaller and fewer graphics and text, while still getting your message across etc.
