Yes, there will need to be an exact time/date announced that will 
coincide with the next planet dump publication.  At that moment,  the 
live database will ODbL and so any diffs extracted from it will also be 
ODbL-published.  Yes, hopefully in a couple of days.  Planets are 
normally published Thursday I believe.  As I think Paul is saying, 
anyone who has their own copy of the database and is running diffs now 
has a clean CC-BY-SA database provided that they shut off the diffs 
before or just before the moment we switch. I believe there was talk of 
changing the URL for the diffs so that any unattended download will cut 
automatically ... someone on the technical side may be able to confirm that.

FYI, for anyone interested, Harry Wood has now posted our collective 
TODO list on the OSM wiki: http://wiki.openstreetmap.org/wiki/ODbL/TODO
