What could easily be added is support for a script similar to the one
in the Users and Groups module that gets run before and after a user is
added/deleted/modified, on each server in the cluster. In fact, the
pre-modification scripts could even have it's exit status checked to
determine whether to do the update or not.  How does that sound?
