What's this commercial license, and what's the problem with CDDL?

[David Ryan]

I noticed that Slashdot had a link today to OSI and the current problem 
of proliferation of licenses.  For those interested here's the link.

I agree completely that the OSI has created a problem for itself with 
license proliferation, however, I don't see this being solved by saying 
that they will only be three licenses (as suggested by the article).  I 
haven't seen these ideas discussed in this list.  Anyone know what the 
meaning behind the requirement for a "commercial license" as the third 
license involves?  What is the basis for this license, etc?

I'm also interested in the so called controversy over the CDDL.  Having 
read over the differences again, it seems to only clarify the MPL.  Is 
there any *real* issues with the CDDL that people have found?  The 
original story is at http://www.technewsworld.com/story/40672.html

Thanks,
David.
