This is exciting! While you can do it now, it would be great if it were easier to view content from a specific WordCamp. Now, you have to find a video from a specific camp, then you can find a link to that camp's video page (unless I am missing something).

It'd be nice if there were a better tagging system, too. For example, it would be cool if you could browse videos based on a tag/topic like REST API, or Developer/End User.

Lastly, I really like Jeff's suggestion to follow a tried and tested model like YouTube.
