Observer mode, listing games on the master server after a game has already started (and removing it when a game has ended) were also projected at some point. We'll need to define a new/extended master server API for this purpose (I suggest either titi or softcoder take on this since I'm not sure I could come up with something which could be easily implemented in the game). Another feature I had in mind was to make the master server export the data as an XML feed, and to not delete all data after games have finished, so that stats can be created (manually at first, possibly automatically later, as in a ladder).
