I've just recently discovered NodeJS -- heard about it for years, of course. I was able to create a web server for one of my group's web apps in about 5 lines of code. It's a bit weird to wrap one's mind around it at first, but then it starts to make a lot of sense. This IPP server is cool, though I'm not sure what uses it has yet. Maybe just a handy way to print to disk without having to choose a folder and file name. Or use as a proxy to redirect print requests to different printers depending on size or type of print job. Or a way to queue up print requests until off-hours. This is just off the top of my head and I'll bet there are other cool uses as well.
