ICC profile distribution licensing costs

This may be a bit of long shot, but I am interested in getting a ballpark number on ICC profile licensing cost that many commercial color profiling vendors charge for distributing profiles made with their tools. i.e. say you are a printer manufacturer and want to distribute profiles to your users, what sort of costs are you likely to be up for ?
