A multilight render takes up alot more memory than the same without -ml. Without a -hd option (I know, its coming) this effectively limits resolution.

A solution to this could be (if it were possible) to allow a -ml co-operative render to divide the emitters in scene amongst the nodes. So in effect each node would require much less memory, but the end result would be the same. Perhaps each node could even be set in advance to handle x number of lights, so if you know a particular node is low on memory you could asign it a smaller fraction of the total number of emitters.

Just a thought.
