Yes they can, but as I vaguely said earlier, daemontools support
will only suit a specific group of daemons, i.e. those who're
pretty independant, and there are other qualifications as well,
such as logging to stdout if you want to use the provided
daemontools logging methods, running in foreground, etc.

Yap, and it can, but as I said earlier, it'd have to implemented
in another layer above daemontools.

Yes, runit was written by the same guy (Gerrit Pape) that converted
the html documentation to man pages for daemontools. I've checked
it out, but I havent used it yet. It might be nice to have a 
runit USE flag too, if it works well. However, for the time being
we also need a daemontools USE flag, since there's obviously demand
for it, and there are services using daemontools now (qmail, djbdns).
