Some weeks ago I was staring to write a small tool to be able comparing result via command line.
However I never finished the work, but if you like I can send you sources but there is still some work to do.
Mike wrote code to do this a while back. It was difficult to upgrade when plugins were added, and no one was using it, so it was removed. But you can still find the code here:
http://cvs.sourceforge.net/viewcvs.py/nutch/nutch/src/java/net/nutch/quality/Attic/
It would probably be easier to revive this code than to start from scratch.
