Hi, I read sometime ago about Sun's ZFS Filesystem and it has been  
described as one of the most "advanced file systems on the  
planet.."  (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.  Just speculating,

Cheers,

Cy
