I didn't see a reason for you not to use CNAME like this, it's not
what you asked for but that doesn't mean you didn't know of the
technique. ;-) I'm just trying to be nice.

There is a slew of reasons not to run SOA from a dynamic ip, not
the least of which is the chance your isp will begin enforcing the
TOS which probably prohibits running a server. And once you are
depending on 2nd dns, it's not really a redundant system, is it?
Suppose, someone in your dynamic subnet gets your ip and happens
to run a NS with wildcards... since there is no requirement for
caching servers to respect TTL in SOA records (it's the start
after all), that server will answer incorrect records for you as
long as it has your old ip. Unlikely scenario, but certainly
possible. http://marc.info/?l=djbdns&m=103505741508241&w=2
I use to run SOA, and still do for private networks. If you are
scripting the process of bringing new hosts online fine, use your
static IP, otherwise it is hard to justify circumventing the
convenience of editing your records in a vcs, and pasting them
into your registrar's dns interface.
If for some reason you don't want to use your registrar's NS, I
suggest you put your primary and 2nd NS on your Xen box. It's less
complicated and less likely to break than a dynamic SOA setup.
