The two efforts I am aware of are rxgk (OpenAFS) and RPCSEC_GSSv3 (NFSv4).

The older of the two efforts I believe is rxgk, and had dual goals of 
addressing the AFS "cache poisoning" problem, and secondarily introducing 
support for separately managed (file) servers.  I believe RPCSEC_GSSv3 was 
initially conceived (by Nico Williams) as a means of addressing the NFSv4 
equivalent of the cache poisoning problem, but the current work on it (by Andy 
Adamson) is as a dependency of NFSv4.2 server-side copy.  (Apologies to the 
participants if I am mis-reporting any of the history.)

The IETF discussion of these efforts is on Kitten and NFSv4.  There's 
interesting recent discussion on the Kitten WG alias.
