We need a persistent post-it, and Documentation/arch-TODO (note the capital letters, we might as well shout?) sounds like a good place. I'd suggest making it tabular, as per the patch below. If it gets too large we can split it into multiple tables. I'd like people to have a good look whether I messed up any entry, and I'd be happy to add new items as well.
