RE: DB copying : Attack of the Clones!

I have not looked into RMAN 'duplicate' method, as RMAN is still not practiced at my work place.
But may be this is the time to consider it. I will do the required reading of manuals etc, but can it move files to other servers as cloned databases will be on different servers (same platform, though)?

Thanks.
