My apologies. I had not intended to write "none", but the note got away
from me before I could edit that.

The problem with NLTSS is that it isn't something we can show people
today. This is hardly NLTSS's fault, but there it is.

KeyKOS was not invisible, but once again it isn't current.

Tahoe may well be production ready. It doesn't address a
user-perceptible need by virtue of being a capability system.

My point, I think is that (a) we need a system that works, and (b) we
need a system that visibly solves a problem.
