Since most cell phones now days are smart phones and have built in IM Clients or you can install them from some sort of app store, I think it would be a tramdous improvement to send an alert to a user through Lync or other IM client. My company uses Lync and I do know that it can be done to send alerts to a set of lync users as Microsoft's SCOM can do this and we really love this feature, even more then the emailing/paging feature as we are not always at our desks to get the email/page. This would be the same for SAM as well.
