Nameserver question...

Why do you want to do it this way? I would certainly feel more
comfortable with knowing that there is at least one off-site DNS
server (I personally have ulv.mcpoolen.se, varg.mcpoolen.se and
ns1.web.tf which is in the process of being changed to
socal.wolf.com).

That set aside, I belive I read somewhere that NS records should not
point to CNAMEs. Don't ask me for the technical discussion behind this
(I am sure others here can fill in that gap), but I think it might
have to do with that a CNAME query response (that is, you ask for a NS
and get a CNAME _and_ a NS) is significantly longer than a single NS
response, meaning that you run the risk of hitting the UDP boundary
and the query has to be restarted using TCP - or a second query has to
be issued for the response to be usable. Which of course means you
need to find the name servers for the domain the CNAME points to
first.
