One thing that I should mention is that if you wish your name to be credited next to the photo license is that you will need to add your name to the 'Author' metadata before putting your images into ICE. There is no way to edit this, once a panorama is uploaded.
Also, for panoramas, the 'Author' field must be filled in identically in all of the input photos for the name to appear. (Photosynths allow a different author per photo because they do not merge photos, but simply arrange them.)
If you do this, people will see your name in the lower left corner of the panorama viewer, wherever your panorama is viewed, which may be good for you if you intend to use Photosynth.net as a professional tool.
