Documentation from the conference

I'm also very interested in videos of the presentations (at least the keynote speeches were filmed) and the presentation slideshows.

you can watch the keynotes here: http://drupalradar.com/
the Internet Archive hosts a few speeches too: http://www.archive.org/search.php?query=subject%3A%22Drupalcon+Copenhage...
I think the rest will be published to archive.org eventually

but bad (as in "mobile phone video") quality, I'm afraid :)

Hello!

Here are our slides + extended online version:

Is there really not a central repository for slides, notes and videos?
