iDisk Sync in PantherA little late, but still strikingly hip. Apple, via panther, has built a caching system for their iDisk technology. Basically, a user's iDisk contents are now mirrored on the hard drive and a directory synchronization is performed upon each access to the iDisk. Or, if you prefer Apple's unfurled description:
Incredible performance and speed
Working with the files in iDisk is as fast as working with your Mac. A copy of your iDisk content is kept on your local hard drive, so there's no delay in browsing your directory, opening files, or saving files.
iDisk for Panther remains visible in your Finder, so it's as easy to access and use as your hard drive. Work on iDisk files without having to wait to upload or download them.
The all-new iDisk architecture keeps a copy of your files on your local hard disk, then regularly and automatically synchronizes any changes you make to Apple's servers. Your latest changes are accessible from anywhere, so if you use multiple Macs you'll have the same up-to-date files available directly from the Finder on any of them.
Offline Access to iDisk
Use iDisk files even when you're not connected to the Internet. When you reconnect, all your changes are synchronized to your iDisk online.
