Re: Reusing the MPL in non-Mozilla projects

Actually, there are a bunch of projects that use the MPL.   The larger 
projects tend to make their own licenses; smaller projects use the MPL.  
Generally the smaller projects don't get as much attention so the use of 
the MPL itself isn't as clear.

There isn't much discussion of this, as we haven't tried to evangelize 
use of the license.   So we don't have a lot of discussions of using the 
MPL.    The CDDL was created for a couple of different reasons, it's 
like the MPL but makes some changes as well.

The MPL is generally considered reusable.  There's an open  question 
about whether to try to take choice of law out of the MPL but that 
hasn't happened yet. 

On promoting the use of the MPL I have  somewhat different view than 
Frank.   I think we want to avoid getting into "license wars" and some 
open source projects are very focused on promoting their licenses.  I 
would like the Foundation to be a voice for finding ways to help more 
code interoperate.    There are a number of people and organizations not 
interested in the GPL, and so I don't see that as the answer.  The MPL 
might be helpful.  I agree with Frank that I don't see the Foundation 
taking on licensing evangelism as a focus.  But I also think that 
avoiding MPL derivatives when possible and having the MPL as a useful 
choice for people who want it is a good goal.
