I recommend that people define "compatible" and "interoperable" 
thoroughly when discussing them, as they can mean different things in 
different contexts. GNU GPL compatibility, for example, basically means 
derivatives of the work can be covered by the GPL.

Having read the current 4.0 draft (and IANAL), I think SA 4's proposed 
database right copyleft clashes with the ODbL's:

I will raise this on odc-discuss.
