Creating such a protocol shouldn't be a hard task, but getting all those server manufacturers to adopt it afterwards probably will be be. ;-) Alternatively, if you can make a good case (and write a decent RFC), you might be able to persuade the IETF working group to add this feature into a future minor version of NFSv4.
