The main reason that this hasn't got a response is because the use case 
is just not clear.

- what is going to happen rsn is that the system admins will produce a 
new planet dump and the OSMF will start distributing that and the diffs 
relative to it under ODBL
- it will only effect data consumers that import that planet file and 
consume the diffs (you are not affected to the point in time you 
actually import the ODBL licenced data)
- if you don't actually publish ("publicly convey") your database and/or 
produced works you don't even have to reimport
- if you have generated tiles from a CC-by-SA planet and don't want 
purge them from the cache you can simply continue to distribute the 
tiles with a CC-by-SA licence (this is btw what I believe the  OSMF is 
going to do)

I'm not quite sure what positive effect dual licensing would achieve 
given the above.
