verbs? Why verbs?

umad. The only thing that is needed is to subscribe to a GSI

normal mads over the umad interface to all subscribers..

With some cleverness you could probably make the subscribe/unsubscribe
fairly general..

Remember SA notifications are not the only unsolicited events that can
occure in the GSI framework.
