Of course, I'm not sure of that and that's why I > asked RMS about it. RMS said, "What I can say about the question of non-free plug-ins is that using the LGPL would definitely permit them." It really all depends on whether Piper is a program using libraries, or is library used by programs. We can specify it either way in the license. I think RMS pretty clearly states that the LGPL will allow Piper, acting as a library to the plugins, to use any kind of plugin. Jeff -- J.W.
