Yeah; I think we're both agreed it's extremely murky :)

My point about being able to sub-licence is pretty specific. If you have 
a license, there must be a licensor. If the person you get it from has 
the ability to sub-license, then they [may be|are] the licensor; 
otherwise, it's the copyright holder. So what I was saying originally 
was that because the QPL has no sub-licensing rights (which are 
otherwise reserved), the licensor *must* be the original copyright holder.

And the original copyright holder isn't offering the QPL. They're 
offering the QPL with specific usage restrictions. I think it's unlikely 
that their distribution of the QPL text with the software somehow 
overrides their licensing wishes.
