Old news dressed up as new news again?
VMWare have offered virtual z/OS (OS/390) solutions for ages now. (That's IBM's mainframe OS in case you don't know). And IBM were quite happy to take the license fees that flowed their way as a result.
I was also using virtual Linux machines (hosted by IBM in one of their data centres incidentally) years before the word cloud began to be bandied about for this stuff, resulting in instant news headlines every time a not-so-new product or service got announced.
I found the precious posts interesting though, for the discussions of security matters, but I would also like to point out that in addition to RACF, etc, any virtual mainframe is likely to be sitting behind several layers of firewalls amd proxy servers if the infrastructure architects have any sort of clue : which is very likely if you're working with mainframe folk.
