Flash will be around so long as Internet Explorer continues to fail to support (X)HTML5 audio and video elements. For clarification the H.264 codec is completely tied to licensing and patent trolls so it is not welcomed on the web or really any where for that matter (and DivX and XVID both are H.264 much to the dismay of many friends). So since IE10 will likely not support the HTML5 video element I think Flash will be used for multimedia presentations well in to the 2030s, I'm absolutely serious.
Furthermore the idea is great but it doesn't work on XP. Since Microsoft lost their marbles and have been destroying all their products (Office, Windows V/7, etc) I can't recommend this. I used a system plagued by the anti-intuitive, cumbersome and slow Windows 7 to run the program. There are demos you can download which makes it easier to understand what you're looking at.
