I keep seeing references to the ufs; who technically owns the concepts
behind the original Berkeley FFS?  And couldn't some other schmo just as
easily come up with a scheme for a "Virtual File System" that wouldn't 
infringe upon Sun's vnode filesystem?

I know the original ufs (read: System V file system) is AT&T property,
but why anyone would want to be stuck with 14-byte filenames and u_short
inode numbers is beyond me.
