For instance, my Libra libraryOS environment currently only has a single channel with which to mount all resources -- so it mounts the file system at the same time as console and network files. I imagine if we ran 9p directly on top of one of the raw interconnect channels on Blue Gene we might be in a similar situation (although we aren't currently looking at that). -eric
