I wasn't involved in their experimental implementation in CITI so I don't know exactly what were their challenges. I can only guess that the harder parts were dealing with the name cache rather than implementing the related NFSv4.1 code. As far as I know, the benefits demonstrated so far are not good enough to justify the added complexity.
