Having a not entirely dissimilar situation (daemon, config file in
/etc, etc.), I have been struggling to determine if my commercial
(non-open source) application can be sold through the Software Center.
Somehow I missed the idea that submissions should be "lightweight
GUI apps". Is that the goal of the Software Center? Is there any way
to sell a commercial, server-oriented (CLI only) package through the
Software Center? Just trying to understand. Any pointers to
documentation clarifying this would be greatly appreciated.
