[PD-dev] Re: [PD-ot] Porting, copyright and licensing

[Hans-Christoph Steiner]

The ACM license does not allow commercial use, so it can't be added to  
the Pd-extended builds.  Currently, everything in Pd-extended AFAIK is  
either BSD or GPL and it should stay that way (any GPL compatible is  
fine).  Otherwise it will create a lot of menial labor to keep track of  
what parts have which restrictions.

There are other reprocussions, too.  For example, both the ACM license  
and Yves' PiDiP license prevent that code from being included in Debian  
or any GPL'ed live CD.
