as I wrote in my initial email, this is understood and not the actual question.

The question is: Is it legal to link ECW with a LGPL (or similar) licensed software?
My opinion is no, because of the described contractiction.

If your answer to my question is yes, what is your comment on the contradiction?
I'd really appreciate a official statement from ERMapper if that is possible.

I do not ask out of simple curiosity - we have a commercial(!) Free Software development
project which faces uncalculatable legal risks due to ECW license.

Free Software is also commercial. Please don't oppose Free Software and Commercial Software.
The opponents are Free Software and Proprietary Software.  Both can either be gratis
or commercial.

done :-)
