Maybe 'report writing' means different things to different people!
In R, using knitr, you can create an entire typeset PDF document
driven by the data including graphics (and animations...).
You write a text document with embedded code chunks delimited by
<<>>=/@ tags. Eg
This is a data analysis.
data = read.csv("datafile.csv")
We can plot the data on a graph
Now knitr can embed python code, and plots created using matplot.
Wouldn't it be nice if that embedded code could be creating map images
in the document from Qgis' wonderful cartographic rendering system?
One way would be for the code to just grab a rendered image from a WMS
server, the other might be to render to an Image using qgis-python in
code chunks of the document.

I'll probably be running around doing Foss4g stuff - hopefully see
people in Nottingham!
