There was one talk called "Tits Bits" at the Chaos Communication Camp 07 (a rather unconventional but awesome tech conference). It was about the technical challenges of operating a porn streaming website. You can download the recording (number 2041) here: http://dewy.fem.tu-ilmenau.de/CCC/CCCamp07/video/m4v/
The recording includes some pictures which make it not safe for work (depending on your work environment).
