Sure!

Let's say there are lots of people with N810s out there. They want some of the goodies in fremantle, but they don't want to buy a new device.

With the community repo, we can backport stuff, like bug fixes, new libraries, etc. to older devices. By first integrating the software into diablo, testing it, then pushing out a new diablo SSU, we can reach people who want to update their N810 or N800 for example.

All of this done by the community without having to wait for Nokia.
