I can see why you would want to hide the nodes that don't actively have memory online, but i still have concerns for nodes that may come and go and hiding this configuration from the user until memory arrives. An example would be a DCD device where a node could add or remove memory at any time. If you removed the last block of memory, the node would disappear - but the block could come back at any time. That seems problematic, as you might want to manage that node while no memory is present. ~Gregory
