I'll try to address the specific features that you have mentioned and tell you
what we have going on. All answers are given to the best of my knowledge so
apologies if something is not exactly correct. I am sure someone will correct
me if I am wrong. ;)
* LIPKEY support - We do not have any projects addressing this right now.
Sorry, I don't have any other information here.
* NFS logging - Are you interested in this for server or client side? Below, I
have listed some things that are coming as well as things that are already in
place. Let me know if this helps and what you other things you need.
- While it is arguably not logging we do have the DTrace Provider for NFSv4
(http://opensolaris.org/os/project/nfs4trace/) project going on. This project
is coming along pretty well. The NFSv4 server side provider is functionally
complete and we have the following steps left: 1. final testing (and bug
fixing) 2. go through PSARC 3. Putback to Nevada
- Also, I am sure you know about it, but nfsstat provides statistics for
the NFSv4 client and server.
* Improved fsid handling for pseudo-filesystems - see below.

Sorry, I don't insight into what the plans for LIPKEY were when PSARC 1999/289
was filed.

Just to make sure I am on the same page with you, is it the configuration
information at the bottom of this page that you are referring to?
http://wiki.linux-nfs.org/wiki/index.php/Nfsv4_configuration
Right, we don't have the capability to set the fsid of the shared file system.
I would be interested in hearing what problem what you are trying to solve with
this, though.
As far as namespace projects that are currently under way we have NFSv4
Namespace Extensions (http://opensolaris.org/os/project/nfs-namespace/)
project. The "mirror mounts" portion which allows a client to traverse the
server namespace without having to do a mount (whether manually or via the
automounter) for each file system shared by the server. Those working on this
may be able to say more, but I believe the "mirror mounts" functionality is
getting close to being finished.
I hope this gives you some of the info you were seeking... Let us know what
other questions or comments you have.
Thanks,
Lisa
p.s. - Also outside of pNFS (http://opensolaris.org/os/project/nfsv41/), here
is another thing that we have going on. It is not something that you
specifically asked about, but may be of interest to you:
NFS RDMA transport update and performance analysis project -
