Hi guys!
packagekit gets more and more attraction, i don't think that i have to explain it here, someone who knows this page knows also packagekit and its possibilities i.e. share package discribtions & news, openoffice.org can use it for the installation from additional packages/art; automatic printer driver download from lsb-site and so on...

Developer comments
Unfortunately the needed pieces didn't come together for PackageKit in Intrepid. Hopefully they may be ready for Jaunty.
