The only drawback is that now we all need a copy of the secret keys on
all machines we're modifying DNS data from...

Personally I'd just make sure the DNS server (i.e. BIND) is
a) running as non-root (except during init, for binding to port 53) and
b) inside a chroot
and set up both permissions and file location of the secret keys in a
way that prevents BIND (and other services) from accessing them, but
allows the post-receive hook (that runs under the user account of whoever
pushed) to use them.

I somehow doubt all our desktops combined are less vulnerable than
lightwave running just a few high-value services.
