I don't think it's impossible, but I think the EROS/Dionysix approach
is probably a cleaner way to provide confinement in a Unix-like system.
I recognize that some things are "now or never" issues. The reason I
added the Emacs paragraph to my original post is that I realized that,
right now, we're on the "now or never" stuff, and stuff that's less
essential can wait until we get to it. I wasn't sure which category
the you-must-trust-the-server decision belonged in, and I didn't want
to waste people's time if it wasn't a "now or never" issue.

The Internet stock bubble didn't burst on 1999-11-08. Hurrah!
The power didn't go out on 2000-01-01 either. :)
