While it is a topic where we'll want to see major stuff going on over
the coming year, I'm not sure that the underlying infrastructure will
meet the GSoC timeline - we're currently in the process of getting the
basics into mainline, and I think it would be a pain to now start
writing larger amounts of codes on something that we'll need to change
