Something like this was implemented during GSoC 2010, but we never got
to merge it to the master branch. I am not sure what the completed
feature set entails and the branch definitely would need a bit of cleanup.

I wanted to get back to this, but there is always something else coming
up that requires attention (as well as the day-to-day work etc.).
Nevertheless, I would be happy to offer advice if anybody wants to take
