This allows storage to be flexible and to change in response to interest among users. Users can access XDegrees resources simply with a browser. In at least one way, the XDegrees system is superior to Jabber's naming system. That means that if you're looking for a file and the closest system with it is down, you can hop to your second choice automatically. The XDegrees technology indicates that the user's machine is offline but that the file is still available on the cache server.
Digests also permit versioning, so people can release new versions of executables and data.
The resource resolution system supports sophisticated searches. Here's where XDegrees starts getting nifty. When someone retrieves a file, it could be cached and served up to other users. Configuration options allow or disallow caching. XDegrees recognizes the concept of user groups, so that for the sake of security you can allow files to be cached on other systems owned by your group and not by outsiders.
