Thanks to Joerg Jaspert, dak is up and running, and Debian developers can upload their own backports.
Enjoy http://backports.org/ !
Backports are recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates), so they will run without new libraries (wherever it is possible) on a stable Debian distribution. I recommend you to pick out single backports which fits your needs, and not to use all backports available here.
