Eh... I'm not usually one to give my thoughts on things this big as I might mess things up, but... Seeing as the IC game world is tightly packed together as it is makes the need for network posts minimal. At this point, it seems like an IC luxury and not a necessity. Most people would just go up and talk to people face to face, so I suggest no network comm.

EDIT: Just read the exploration thingy toplevel and... actually, that might require the use of network as people might be too far away for many others to interact with them. If you go through with exploration plots, then there might be a need for more network and thus a network comm.
