Problem with sockets is read & write aren't the only syscalls that let you
send data. There's also the send*() and recv*() families of calls. In the
case of {send,recv}{msg,to,from}(), that sockaddr can change (imagine a DNS
server, e.g.).
Your best bet might have been the IP provider, but then you don't get UNIX
sockets or the generalized file-descriptor intercepts you seem to want.
