Scalable web apps, maybe, but "network programs", I disagree. Just spawning a bunch of Node instances is insufficient to really scale in many network apps, you also need a good way to communicate between them. Preferably one that hides the fact that you are communicating between separate machines. For the most part, web apps can get by with pushing this to the DB but I think it's a bit much to say this is acceptable for all network programs.
