I haven't seen many control panels that offer a free one domain licensing option but I think it would be a good market for DA to move to. You get someone to download, install and configure and hopefully use DA by doing this and they will eventually see how good of a product DA is. After a month or so, they're bound to add another domain to their machine and will want to upgrade their license. Just a thought. Also I think DA should be offered free of charge to official Open Source projects. This way DA is giving back to the community that made it possible. Just a couple things to think about.
