[ih] RE: from your DRS perspective?

[Steve Crocker]

I think there was, in fact, some preliminary implementation of NIL, but
it wasn't completed and the effort was abandoned.  I don't believe it
played any part in subsequent developments, e.g. NVT.  Jeff Rulifson and
Bill Duvall were the key people behind NIL; they're still around and
could be tracked down.  Jeff was at Sun the last time I saw him.
