30 minutes is very short -- that's the length of my Python talk about packaging.
In order to give a chance to people that could not make it to Pycon, or for those who won't be able to ask them during the talk, I have created a Moderator here: http://bit.ly/pycon2010
Add questions there and vote for them -- I'll answer to them at the end of the talk if I have spare time, or in my blog.
