That is probably a bit beyond reasonable levels of scaling. For one thing, putting 100,000 machines close together in a network is a bit tricky. The two major limitations are likely to be memory for keeping the watches on the server side and bandwidth for publishing the notifications.
That said, ZK is solid enough that I would not be surprised if it scaled to that level with sufficient memory and low enough update rate.
