I&#x27;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&#x27;s web apps in about 5 lines of code.  It&#x27;s a bit weird to wrap one&#x27;s mind around it at first, but then it starts to make a lot of sense.<p>This IPP server is cool, though I&#x27;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&#x27;ll bet there are other cool uses as well.
