When you look at the krprotect tool... There you can set branding free.
When you have that license, the ' more about krpano' in the context menu is not there.
That's the only thing.
This is also on html 5.
You just make your own henrik.swf and henrik.js with the protect tool and use that as a viewer.
You can give also some extra options like expiredate, or disable javascript etc etc..
Customize your own viewer as you like.
Hope it helps.
