If I read your OP correctly, one of the major issues confronting developers is that organization's won't permit downloading just any old module. I know I've encountered that with a number of my customers. If it isn't CORE, then there better be a very good reason to install/upgrade it.
So if there were some add'l level of "trust" involved, i.e., a certification, then that issue might be eased. And part of the requirement for a Certified Module is that the module author has explicitly agreed to release the module to whoever administers certification for maintenance. One can imagine many other baseline requirements (e.g., it must use the normal build/test/install make process, it must have a test suite, it must explicitly specify which versions of perl and prereq modules, and on what OS's and/or platforms, it is certified for.
Of course, there's the little issue of funding... I doubt there's much of an opportunity for commercialization of the process, and it will cost money for all the h/w and s/w, not to mention staff to run this. But hey, if OSDL can survive, maybe there's room for another such org ?
