check out Scripteur, a cool OSX only solution to media publishing. If you’re a mac only household and you want to share MP3, video and other files seamlessly across your lan to the other machines on your network, this may be good for you. It’s a clever use of Rendevous and Applescript. No Tivo-like recording functions or anything, this is only about publishing, but what it does it does well.
Rendevous is cool stuff and one of the cool things to be found on OSX. It’s based on Zeroconf, an international standard for zero configuration networking. Apple is as far as I am aware the first big vendor to support it, though some of the printer manufacturers are following along in Apple’s wake. The idea is network devices should be able to autodiscover network services, so you plug in a new PC and it finds the DHCP server and all nearby printers. You turn on server on that box, like FTP or HTTP, and any other machine on that network segment can see the server without having to know its address. It’s really pretty damned slick. Just cross your fingers MS gets around to incorporating it into windoze so apps like Scripteur can work seamlessly across platforms.
