I personally encourage .u, namely because 9p.ko supports it, and
thus filesystem servers can provide things Unix users expect
(e.g., symlinks). The whole uid/gid number thing, though, should
definately go. They cause way more trouble than they're worth in
a networked environment.

The programmer, like the poet, works only slightly removed from pure
thought-stuff. He builds his castles in the air, from air, creating
by exertion of the imagination. Few media of creation are so
flexible, so easy to polish and rework, so readily capable of
realizing grand conceptual structures.
