There is at least one other user that I know of, which is the ehea driver. They're running through patches now to use it. Anyway, we need the notifier. We're only going to get more and more drivers that need notification. There may be one user now, but that's no reason to rip it out. Feel free to revisit it in a year if there's still only one user. :) -- Dave
