Real estate is the only type of property I'm aware of that allows the owner to enter into covenants that "run with the property." As of yet, I haven't heard about any exceptions. Software licensors have tried, but so far haven't been successful AFAIK.
The Supreme Court reinforced these doctrines just a week ago (in a patent case, but the same principles apply), ruling against Lexmark printer cartridge restrictions "that a patentee’s decision to sell a product exhausts all of its patent rights in that item, regardless of any restrictions the patentee purports to impose."
