yes, and I would add backports.debian.org

well, I agree with you. It's frustrating for the Debian people (at last for 
me) cannot compile (or create) the debs packages of ros. Also, I would like to 
introduce the problem that for a system admin, like me, ros works so well in a 
box alone, with one user that it's also root(sudo), but it's not easy to 
maintain a group of boxes with ros if you don't want to give sudo permissions 
to the users.
