Awesome, I'm still kicking it around in my head...but, yeah. There's a lot to chew over with it on several different levels. And since there's a number of reality tv shows that push my squee buttons, it is Relevant To My Interests. I haven't really worked with RPF, but I suspect a lot of the ethical challenges are similar to reality tv regarding where the lines are with people who do not conveniently go back in a (metaphorical) box when you are done playing with them. :)

And also, the technical and artistic challenges as WELL. Because you're dealing with footage that is...well, not always exactly ideal in translating to vid form, and tricky to cut.
