1. The design concepts of SAC are freely transferable to any other language, or even to another implementation of the same language.
2. The licensing terms of SAC are, I believe, primarily intended to keep the lawyers away from the SAC crew. 3. The licensing terms of SAC have been under review for some time now, and are likely, I suspect, to become more liberal.
