Openfire plugin for Service Administration ad-hoc commands?

Has anyone created an openfire plugin to provide some of the unimplemented XEP-0133 Service Administration ad-hoc commands?

Specifically, I’m looking for the capability to remotely enable/disable a user using an ad-hoc command as specified by the

admin#disable-user or admin#enable-user examples.
http://xmpp.org/extensions/xep-0133.html#disable-user
Alternatively, if anyone knows a way to perform these tasks remotely via the Smack API or other means,
I'd like to hear about it.
Thanks,
Tim
