I had to install ownCloud on Zentyal myself, make sure it didn't break anything, plug it into mysql, watch the updates... then watch the Zentyal devs go in a direction few freeloaders had need for, but, the machines are still doing what they were built for and are still updated with security fixes, with NS it's all taken care of.
Point is, the best way to ensure people spend their own time building what you want for you, for nothing, is to go to their home, and then snivel and bitch that they haven't done what you want.
