    Subject: the Plan 9 Foundation


    We, the creators of Plan 9, are writing to you in support of transferring the Plan 9 IP to the Plan 9 Foundation. The transfer will benefit Plan 9 users both outside and inside of Nokia. Outside use and development has been stifled by the confusion around the current LPL license. Inside use is discouraged by a lack of community involvement and support. The Foundation has been founded to maintain a ’common root’ under a less encumbering license such as the BSD or MIT ones. This root will provide a stable platform on which users can further extend and customize the system.
