In Inferno (and Plan 9) it appears that network devices are filesystems -- e.g. there's a /net/ether0 directory which contains files with access semantics corresponding to various configuration and throughput tasks. I've read that it's even possible to 'mount' a remote network device on top of a local one, effectively tunneling traffic through the remote system. It's an interesting concept but I'm not sure of its utility, having never really used it.
