In in theory we should then be able to Screencast the development work without having to use our camera phones to record the screen on a big TV, etc..
Don't know about the rest of it, but the web interface has a utilities/screenshot function.
What I mean is a way to Screencast the experience rather than screenshot a single image. So for example, you can browse your channel using your remote, but you are viewing it on your computer. So then you can record your desktop to produce a video of you browsing roku.
But either way, this isn't the true goal but rather a nice side effect. My true goal is to be able to develop and test, all on the same laptop...eliminate the need to have the roku device plugged into TV. The setup that I described seems logical...i just can't find any record of anyone doing it.
