Note: there are many more commercial products using OPAL. However, unless we get explicit permission from them, we cannot put them up on this site. Usually, this is because the people involved are "too busy" to make the decision. Sometimes, the product or company is now defunct. And occasionally, the company is a little embarrassed about using Open Source and don't want it known. Do not assume that this is by any means an exhaustive list of all products using OPAL.
