The GPLv2 doesn't have to cover this distinction to make it a reality. This distinction is *EXACTLY* the type of distinction a lawyer will make when arguing the point. Yes, it's artificial. Yes, it does appear to violate the GPLv2 - *IF* you read the text of such in a specific manner. However, the GPL, until version 3, *NEVER* guaranteed the right to run a given piece of software on *ANY* hardware - not the hardware it *COMES* on. And please, I repeated myself only because your reply seemed to imply that you didn't understand the statement I had made. Since you have now informed me, in a backhanded way, informed me that my interpretation of your response was wrong, I will not repeat myself again. Also note that I have re-examined the facts, in light of new information presented in this discussion, and have come to the conclusion that devices like the TiVO, in keeping the signing keys private (because of the "Facilitation of a Crime" thing I noted earlier), is violating the GPL, but not in the manner almost everyone is arguing. The violation is, rather, with the clause about the license being null and void in event of laws impacting the delivery of the source. (Because, as I also stated earlier, the signing keys are part of the source. Since, in some cases, the license on the hardware prevents running modified binaries (a reason for the digital signing) companies will keep said keys private - doing otherwise can (and I can assure you that some lawyer will do this) be construed as "Facilitating the Commission of a crime". In this case, it'd be "Breach of Contract" - IANAL, but IIRC, licenses fall under contract law)) DRH > > cu > Adrian -- Dialup is like pissing through a pipette.
