Actually MapOSMatic and OCitysmap (and the rendering daemon) only
"communicate" through a database. This allows for the web service to run
on a machine independant of the rendering pipeline (that's also why the
local path to the renderings is configurable, so you can have a network
mount from the machine hosting the renderings for example).

Having this kind of file is only possible if the two reside on the same
machine. Thus the only solution is to extend the Django model for the
rendering jobs, which would then be filled in by OCitySMap as renderings
are completed, so they can then be displayed from the web application.

Good idea though, but that's obviously low priority in the grand scheme
of things that lay between us and putting dev.m.o in production.
