Well, I'm not sure I agree, but I'll wait for Alex to speak to the 
issue.  It's not my intent to change the practical effects of the OVPL 
(copyleft open source community with extra ID privileges).  Rather, it 
was my intent to change the philosophical underpinnings of the license 
to be more open.  So from a principled basis, perhaps it's a big shift, 
but the practical effect is intended to be quite small.  Indeed, there 
should be no practical difference unless the ID loses the faith of the

I looked on, but didn't see the Copyback License 
mentioned.  Is it OSI approved?

But if as you say the Copyback license allows anyone to make prorietary 
derivative works (like BSD), then I don't think it'll work for me.  What 
I'm looking for is a license that binds the open source community with a 
GPL-style copyleft, but gives the ID the exlusive right to create 
proprietary versions.  So far as I can tell, this is essentially the 
goal of OVPL, and my proposal is to satisfy this goal while upholding 
the open source principles.

Regardless, I appreciate the suggestion.  Thanks!
