Having followed the discussion, that's my conclusion too. As a free- 
standing license I don't believe it would qualify as Open Source  
because of that initial period where the four freedoms are not  
available. I'd be surprised if the OSI Board approved it. That's not  
to say a company attempting a business model on this approach would  
fail, but their software could not be described as open source until  
the initial period had expired.
