UPDATE:
Presentation from Usenix now available here
So next week, April 10-15 to be exact, is Usenix '05 in Anaheim, CA. The program committee was generous and asked me for an invited talk on NFS version 4. If you have plans on attending Usenix, stop by. My plan is to cover the internals of the protocol itself with some of motivation behind the feature set. Will cover where NFSv4 is available today and finish with a list of future enhancements that are being discussed in the IETF Working Group. Also, look for the Solaris BOFs. I should be at the BOFs and will certainly be available after the presentation for questions.
