It could certainly be done that way, at least on a case by case basis.
I believe, though, that writing a script that would execute correctly on
any Unix, Linux, Windows, etc, platform is probably not feasible!
The better way to do it for all platforms would be to add code to modify
the proper data structures to allow ntpd to accept reply packets from
anything declared as a server or peer. I believe it's on the "to do" list.
