I'm not sure about you guys, but I'm rather partial to the Gnutella network. My favorite app for accessing it is here:


It's got lots of great automation features, and is very aggressive about downloading the files you tell it to - the design goal is for dialup users to be able to give it a list of files to download, and it tries to get those files relentlessly untill you tell it to stop, so you can safely leaving it downloading overnight, without worrying that the download got cancelled or failed in some way. Works great for broadband people, too
