I believe you should be able to lock Brewing Stands, MInecart with a chest, and MInecart with a furnace. Brewing stands because I'm afraid that my potions will be stolen. MInecart with a chest because its a chest. MInecart with a furnace because I like to transport my coal sometimes and I don't want it stolen.
Um oops. Thought you wanted this topic locked. I'm not sure about brewing stands as they do not move. We have been able to lock other items besides chests and doors, so it would be nice to lock a brewing stand. Minecart's however are out due to what has been said already. RagMan
I too would like to see brewing stands being able to lock, but it might not be possible, as there is a new block with every bottle you put in, so this may screw with it, I will look into seeing if this is possible though as it would be a nice addition. and I feel all tingly inside because I was quoted saying something smart for once XD
