(Plan9 notwithstanding :-)). Among its many features are a set of flexible, dynamic and complex snap-shotting capabilities that sound very much like the technology that could underly Apple Leopard's new back-p capabilities. This is all the more interesting in that ZFS was and has been vigorously discussed within Apple as a contender for the successor to the hybrid HFS+ OS X presently labous under. As Steve Jobs announced they were deliberately not going to announce several key Leopard technologies this could be a possibility.
