I know this post is originally from 2008, but I want to make it clear that the licensing terms have changed since then.
As of March 26, 2012, the
IdeaBlade Product License Terms and Conditions, indicates in section 1.1.1 that,
"If You select the free Trial License, You are authorized to install and use the Software for the sole purpose of evaluating its functionality and performance. You may not integrate the Software into end products or use it for any commercial, productive or training purposes. You may not redistribute the Software or any part thereof."
