And `nsupdate` basically assumes that TCP is available - it doesn't give the caller a way to find out what the server's maximum update size is. (Similarly, my `nsupdate` wrapper `nsdiff` also assumes transactions can be up to 64KB in size.) So I think you'll be sad if you try to deploy an UPDATE server without TCP.
