W.r.t. Sphinx: Conceptually it's really nothing that fancy, just some Python glue code that takes the data structures out of my web application's data structures, and puts it together such that Sphinx can understand it: The only interesting part might be that there is an internal front- and backend separation [based on ZeroMQ] which helps me to create workers which do the actual conversion.
