hmm, I am not an expert on software licenses, but I understand this paragraph slightly different:
If you want to integrate it in your commercial products, you'll have to get a commercial license. There are some exceptions to this rule for Public Research and Education labs. Non-profit web sites that don't want to publish their source code under GPL may also apply.
Limesurvey might be used for commercial purposes, but it is not a commercial product, as it is not sold. I think this has no impact on Limesurvey, as it is distributed free of charge with source code. How you use the product should be not the problem.
However, I can be totally wrong in my interpretation here, as I am no expert.
