"agreed to back" would mean having a subforum here, a reference in the homepage perhaps, the wiki pages that the own XYZ devices users would want create... That's it? Each product would have the life span their own users would like to give it.

The bottomline is: could other devices feel at home here?

Note that the boundaries are already blurring at the app developers levels, with the discussions around the Community OBS and the possibility of having Fremantle, Harmattan, Mer, etc targets hosted in a same server and compiled by the same build infrastructure. The technical solution being discussed can have one frontend for multiple targets (as an evolution of http://apps.formeego.org ) or it could offer (afaik) separate frontends for different targets. Independently from this, each product could have their own related client, like MeeCatalog for the N9.

Another way to pose the same question would be: does maemo.org have an interest in becoming a user space for the platforms / products using that Community OBS?
