Yes, it seems Linux will finally get a single packaging format that should work on all major distros and their derivatives. That´s not exactly what it is technically speaking, but end users will experience it as such.
After a meeting recently held in Germany, relevant members from Fedora, Ubuntu, Debian, Suse, and Mageia projects agreed on a number of interesting ideas. To quoute Richard Hughes: "The idea of the conference was to talk about defining some APIs we can share, to discuss interchange formats, and talking to the UI designers to make installing and removing software on Linux suck less." You can find more about this interesting meeting reading Richard´s own blog entry HERE.
In addition, if you are REALLY into this subject, they uploaded a video of the presentation, shown below (Gets pretty technical, consider yourself warned!).
