The call for papers is almost over. If you want to speak, please send in your abstracts soon.
I started writing up some code to add RPM support to Nautilus. At the moment, I just have a simple GNOME VFS module that allows you to see what packages are on the system. You can see a sample of what it looks like here. The package sizes represent the installed size of the package (as reported in the RPM database), and the modification times are the installation times of the packages.
I still need to write some code so that you can view information about the package (probably as a nautilus view), and some utilities for installing and removing packages (these will probably be separate applications, which should cut down on the problems I ran into when writing GnoRPM. When it is finished, it should be pretty useful.
