Getting Windows itself to do it is a lost cause, of course.
I can do it via scripting a call to a win32 build of nsupdate and
wrapping it as a service, but was hoping someone already had built an
equivalent solution that wouldn't be as hacky.

I'm setting it up so that there is a key per subdomain in the dynamic
zone so a given client has control over A and TXT records of their own
personal subdomain but nothing else, so it's not open for abuse. It
works happily on Linux via dhclient's support for Secure Dynamic update
