sentences:  Mono architect Miguel de Icaza blogged that the Mono team prototyped Moonlight multimedia support using the LGPL-licensed FFmpeg engine but that they were unable to redistribute packaged versions that used that library due to FFmpeg codec licensing issues inside of the United States.After the release of Moonlight 2, a covenant provided by Microsoft was updated to ensure that other third party distributors can distribute Moonlight without their users having to worry about getting sued over patent infringement by Microsoft.This covenant can be found on the Microsoft website.
