I certainly agree there are many similarities. My only concern is with some of the other support that doesn't make sense wrt to sockets. Take for example the reset device call. How would that map into a sockets interface? Maybe we can take the meat of the API and implement by means of a sockets API where it makes sense, and make everything else use an ioctl interface (or something else)?
