I'd like cross-distro packaging to become much easier. Most projects that bother to provide Linux binaries at all typically only do Ubuntu packages. That's fine with me, as I use Ubuntu, but it would be great if there was some new packaging format that worked across distros, that would be so ridiculously easy to use (from both developer and user sides), that there would be practically no reason not to do it. I guess this would require some definition of what libraries are included in the system and things like that, but the few popular distros today are quite similar anyway.
