Martin,

I gather you are suggesting this be a method on the GDALDataset?  
I am pretty hesitant to add new virtual methods on the GDALDataset
unless I think they are really important to the data / access model. 

The CPLSetConfigOption() provides a mechanism to control it, but not
in a dataset specific manner.  Were you wanting to be able to request
particular datasets to use one kind of overviews, and particular others
to use a different kind of overviews?  

I think I might be better off extending the BuildOverview method to 
include an options list.  

Best regards,
