No, that's not even an option... because then Pipers users wouldn't be allowed to use Piper commercially (as it would imply using the library commercially). This license is NOT compatible with the L(GPL), so it would be illegal to redistribute Piper if it links with this library (whether or not the library is separated from Piper). I'm no lawyer, but I've looked closely at the GPL a couple times. Jean-Marc -- Jean-Marc Valin Universite de Sherbrooke - Genie Electrique valj01 at gel.usherb.ca
