Hi!
here I leave you an Ctc interview from the father of MPL. In his opinion it is marvelous.
In my opinion there are so many questions in the air and a lot off things to define with this licence.
Like "contact approach" says ,we should think it very carefully.
However the best opinion would be that of the guys who have already done it , some things that I could hear from them, is that they were very happy.
