In the past when I've done this, I've done it in the sockets layer by
doing a lookup on the socket.  If it's not one I know of, I pass it
through to the OS and expect it to either handle it (if it's a file
descriptor) or return an error.  This worked pretty well.  We can't
easily do this in lwIP though as it's rather OS specific, and so up to
the porter.  We could, I suppose, provide hooks for the port to use to
provide this functionality.
