Dear Marc-André and Vic The most well-known way to show that something is not a derivative work is to do a clean-room implementation [1].
Can I ask what steps you have all taken to ensure that your knowledge of the old FreeRDP 0.x and rdesktop code-bases does not cause FreeRDP 1.0 to be a derivative work of those code-bases? Clearly you are not following a "clean room" type arrangement given you have all seen all the code before. Thanks, Stu.
