Well, if I remember well, there was this little nifty legal argument between ATT USL and UCB BSDI in the early '90s that was settled out of court. One of the factors that helped settle (again if I remember well) was that ATT had failed to adequately state its Copyright on UNIX version 32V (may be more, my memory's weak) that had been distributed in source code, and hence those sources by the then current Copyright law, had fallen in the Public Domain. Then, if my recollection is right (better look at the documents on the case available on dmr's web page), you could do as you well damn please with those sources. http://cm.bell-labs.com/cm/cs/who/dmr/bsdi/bsdisuit.html "Consequently, I find that Plaintiff has failed to demonstrate a likelihood that it can successfully defend its copyright in 32V. Plaintiff's claims of copyright violations are not a basis for injunctive relief." For others, the license otorgued by Caldera when they released the source (a BSD look-alike) would allow you to as well to a large extent. No need to go to the Open Group. Besides, they own the trademark (i.e. you could not call the product UNIX without their permission) but not the code (besides their own microkernel developments). j ______________________________________________ Renovamos el Correo Yahoo!
