The fine print on iFS is interesting as well -- the best the previous version could do was to deliver content at about half the rate of NFS (IIRC) on a comparable machine. I don't know whether they've fixed this in the current version. Storing the metadata and the content in a database apparently caused the slowness, although Oracle felt the drop in performance was acceptable given the added functionality.
The alternative is patented by IBM -- put hooks in a traditional OS so that the file system is kept in sync with the RDBMS. Usual OS-speed for simple file service + fancy games with metadata queries for other applications.
In general, populating directories based on queries and providing a file's metadata from a real RDBMS is an especially cool idea, especially if you don't simply recreate the usual static hierarchy of directories. It makes the file service part of systems like the Streams from MirrorWorlds/Yale trivial. The Placeless Documents folks (probably at FoRK # = 1 or 2 so they can correct me if I'm wrong) did neat things with this idea at Xerox PARC as well.

Extensibility was a schema-editing tool. Isn't it rude to refer to such
a tool as "industry-leading" in a press release?

"You have asked me how I feel about whiskey -- if, when you say whiskey, you mean the oil of conversation, the philosophic wine, the stuff that is consumed when good fellows get together, that puts a song in their hearts and laughter on their lips and a warm glow of contentment in their eyes; if you mean Christmas cheer; if you mean the stimulating drink that puts the spring in the old gentleman's step on a frosty morning, if you mean the drink that enables a man to magnify his joy, and his happiness and to forget, if only for a little while, life's great tragedies and heartbreaks and sorrows, if you mean that drink -- then certainly I am in favor of it."
