Configure 5-10 custom namespaces for different genres / topic areas.
I was thinking it would be easier at first to develop several projects as namespaces, which might be easier to support socially, and then "graduate" the more developed ones over time. Especially for the low-tech "spores".
Maybe we can close it, and open another one for the fancier namespace extension if we ever get to that. Indivisual namespaces are easy enough now that maybe we don't need to track on phabricator.
