NetCitadel's dual licensing

[Oxwivi]

FirewallBuilder runs on a variety of different operating systems. Linux, Mac and Windows versions are available. Therein lays the unique twist on the dual licensing model. Where some commercial open source companies enable or disable certain features to distinguish between the open source and commercial versions, NetCitadel does not. Other commercial open source models will limit the amount of devices that can be managed or threads opened or some other such capacity limiting formula. NetCitadel does not. For NetCitadel the difference between the open source version and the commercial version is simple. If you run the product on Linux, you get to use the free open source model. If you run it on Windows or Mac you have to use the commercial version.

What if you compile the source code on a mac? :lol: Under most FSF approved licenses, that would still be legal :p
