DropBox
Dropbox is an app/webapp that allows you to share files across multiple desktops. The flash demo on the site uses a Windows desktop and a Mac Desktop for the demo (No mention of support for *nix boxes). From the demo it looks like you can ‘publish’ a directory and then have other systems you use subscribe to these published directories. You can also allow other users access to your published files. All of this seems to be controlled from a web interface on the site.
A couple of cool points that I liked were the ability to undelete files from the web interface and revert back to a previous version of a file and only sending the delta of the change between hosts (thus saving bandwidth)…
Anyways…worth a look if your like me and constantly send files here there and everywhere =)
