[gdal-dev] Spherical Mercator projects and overviews?

Hi all,

I have a question regarding imagery in spherical mercator projection in 
geotiff images. Do overviews work correctly?

For example, I use EPSG:4326 and build lots of overviews and I can zoom 
in and out and pan without a problem. Can I do the same thing with 
EPSG:900913 (spherical mercator projection).

I'm working with LandSat imagery over large area and scale ranges.

Thanks,
   -Steve
