The only thing I see here that can't be done in dhtml is recording. Everything else has prior art in a browser without resorting to flash. So, as I said above, use a hidden Flash component to handle the recording (and the timing if you can't make it work with intervals), but do the display and manipulation in the browser itself. It's not particularly hard. I've personally done most of it on past projects. With a bright team, it's really not any more effort than doing it in Flash. Try not to read what I said above as a knock against the product. It's pretty cool. But because it's written in Flash, it's no more technically spectacular than the dozens of Windows and Mac versions of the same thing, so it probably doesn't need to be posted here. In other words, Flash has advanced to the point where it's no longer newsworthy that you can build things with it.
