for the full story about licensed programs issues You should join and lurk the hercules-advocacy forum on Yahoo
all the attempts to get a <hobbyst> license for zOS and friends have been curtly dismissed by IBM,
so it is not important what we would like but rather what IBM wants .
I dont think IBM ever will stop a private person from trying to learn z/OS, using a copy of their ADCD z/OS package run on the Hercules Emulator.
strange enough the ADCD, now zPDT seems to have more explicit contractual terms for the allowed platforms.
IBM might not be able to stop private people from using licensed products ( on any real /emulated hardware )but it might be certainly able to do lots of damage to each one of the hercules developers ,
at least to those whose name is in the copyright section of the hercules sources ( and mine is in some of them )
the issue is even more murky about IP ( intellectual property ) violations
according to some school of thinking even writing <software> which reproduces the functionalities described in the POP
might constitute an IP violation
this is the reason of my getting pissed when I see people telling about using licensed products on unendorsed platform
might sound hypocritical, but for my own protection ( what I do not know will not bite my ass )
You got it, You use it, just shut up about it, if You have problems live with them
