This is possible with the 2.5 licence and above and should definitely be used.

"If you distribute, publicly display, publicly perform, or publicly  
digitally perform the Work or any Derivative Works or Collective

provide, reasonable to the medium or means You are utilizing: (i) the

Derivatives of BY-SA works can use later licences, so OSM could update  
to 3.0 or 3.1 whenever more data is added (in theory. IANAL).
