Most YC events are now live streamed on Justin.TV. I think this leads to extremely low quality video feeds and incomprehensible audio. (Please see the last year's video archive). Given that a large number of people who apply for the startup school are not selected to attend it I hope that there is some way that YC could provide a higher quality video feed.
And while you're at it, can Y Combinator put live streaming in nearby classrooms at stanford for those who didn't get accepted to this year's startup school?
It would be great if YCs video library were available as an RSS/ Podcast stream so you can watch it in iTunes, or on your Zune like TED videos are available.
