In Windows NT device objects get instantiated in \Device, including network cards. Also, different TCP/IP layers are accessible as well, like \Device\Tcp, \Device\Ip. In Unix the network stack is not accessible in the file system at all, there's nothing in /dev, it's just a special API in the kernel. In Windows you'd use a networking API as well, but the networking API is a convenience layer over file based I/O. The difference between Windows NT and Plan9 is that Windows NT device I/O is IOCTL based, not composable, not replaceable and not exportable, but it's just how you'd do things in Unix v7.
