> More modern version (the one that come with zPDT emulator package) cannot be pirated anymore. I don't think it can't be pirated. IBM has made it a bit harder (DRM encryption of the installation media), but nothing a sufficiently motivated and skilled person couldn't bypass. However, I guess that extra difficulty has been enough to dissuade people from actually doing it, thus far at least.
