Do you need to ICE each remote server? Or does the cards in the remote server section count as only one remote server and thus need only one set of ice.
ie. Corp has a face down agenda card and a face down trap card. Do I need a set of ice for both the agenda and a set for the trap or does 1 set of ICE protect both cards?
You never *need* ICE. ICE is there to make it difficult for the Runner to Access the Server. You can play cards into Servers and not ICE them, you can play ICE protecting an empty Server, and you can not play ICE in front of your Central Servers if you so choose.
So you could have several different Remote Servers, especially since you cannot have an Agenda and an Asset in the same Server at the same time.
