Business Rules - SMS notifications

Hi
Could a business Rule be created that would notify a technician via SMS of a particular incident/request. I am aware that "Notify technician by sms when request is assigned" could be enabled but then that would be all requests which would not be suitable.

I appreciate that we could create another technician just for SMS notifications but again that is not ideal.

Has anyone else got a need for this, i.e. something to warn you when your server is about to crash or the Air Conditioning in the server room has failed and your at home enjoying your weekend. I realise that OP Manager and MOM can take care of things like this, though I would like to bring it all together using the service desk.
