Clever Mac Stuff

I found a neat toy last night for my Mac. Hydra (although they’ve actually just stopped calling it that) is a collaborative editor. It does all the usual nice editor things, like syntax-highlighting, document navigation and so on, but it also has a rather unique feature: more than one person can edit the same document at the same time. You can share the document, and have other users edit along with you, with your changes being highlighted seperately. It does it all without a server, and using standard things too (standard on OS X 10.2 at least).
