The nowjs paradigm of functions that can be called back and forth from server and client is really inspired.
In my experience, the underlying "
socket.io" module is not able to scale well (more than 150 connections was a problem for me), so I had to retreat from using "nowjs" or more specifically, "
socket.io" in one of my applications. On the other hand, I have another application that has been running for 9 months now without any problems, but it only handles 2 to 5 connections at a time.
My other observation is that: The magic pocket for variable (across sever and client) is not useful, because it does not have any notification events (ie onUpdate, etc.), so you never know when the magic has occurred.
