How Do Your Machines Talk to Each Other?

VonGuard asks: "I'd imagine this is a common scenario out there for Slashdot readers: I have multiple desktops, all sitting right next to each other and all running different OS's. Linux, Mac OS X and 9, Windows 98, and XP. The problem is, despite these machines being only inches arpart physically, in the digital world, they are miles apart. I have no single way to get them all to talk to each other. NFS is impossibly complex, Appletalk is unreliable thanks to netatalk, while PCMacLan, and Samba make me feel like I'm giving into the Empire. Isn't there a simpler way to get files from one of these machines to the other? Right now, I use webservers and write little HTML files that link to the files on each machine. Isn't there a better way to do this?" Is there really a network sharing standard that works across a number of operating systems aside from Samba? Truth be told, Samba "works-for-me", so that's what I us. However, when it comes to simple file copying, sometimes a simple scp is all I need. What protocols do you use in networks that consist of 3 or more operating systems?
