FYI: Since PiDiP was started by porting EffecTV to PDP, PiDiP inherits EffecTV's GNU GPL license.
http://ydegoyon.free.fr/pidip.html
http://sourceforge.net/projects/effectv/
Such is the infectious nature of the GNU GPL. While PiDiP might be able to be offered with another license, the GNU GPL requires that PiDiP is also available under the GNU GPL.
