XBMC is free and open-source software, meaning that it is generally acceptable for any company to use and distribute it as long as our license is respected — we do not charge any licensing fees. However, in order to foster a healthy relationship with the XBMC team, we ask that interested parties open a line of communication with us first. This is only a courtesy of course, but we appreciate knowing where our project is used. We may even be able to help you with your plan!
We also provide the option for companies to become official sponsors (see the sponsors banner on our front page). In addition to the satisfaction of helping the open-source community, sponsors are entitled to some special perks as well. We strongly encourage anyone using XBMC as part of their business model to sponsor us in some way, though you are welcome to keep the details private if you wish.
Please understand that we cannot give legal advice regarding your possible implementation of our software. Multimedia licensing/copyrights/patents are very tricky, please contact a software attorney for help with these questions.
If you would like to discuss your project in more depth, please contact us and describe the project and its scope as much as possible. We are always happy to work with companies who wish to include us in their projects.
