Chuck Lever - Jan. 20, 2012, 9:21 p.m.
Last year, Microsoft made a formal IPR for technology described in
the FedFS NSDB draft.  At IETF 81, NetApp formally announced the
existence of a patent which covers FedFS-related technology.

Split out a new section for IP disclaimers in our README file, and
document these patents.
