This thread has gone to be centered around the GUI of R and what it is 
good and bad.

However, is the above statement correct? To me it seems like there is a 
fully working R-proxy dll for windows and other ways to interface 
against R that only binds to LGPL components. You can build completely 
proprietary packages and front-ends to R without having to make sources 
available, as long as you distribute changes to R itself as source.

In my opinion anyone can be to R what S+ is to S. Can any developer 
comment on this?

    Best regards,
