It's funny, I just started working on something very similar for our Windows
Networker server myself. It's not done yet, but I hope to further organize the
savesets so that the VTL tapes to be cloned from are loaded a minimal number of
times, a la "clone everything off this tape, then clone everything off that
one" etc etc. I'd be happy to post the working copy (when it's done) if anyone
is interested.
