The article had Diane Greene, VMware's CEO, saying that her company's existing x86 desktop product is already being used by some to run Mac OS on computers from Dell, HP and others, though this was not intentional on VMware's part. http://weblog.infoworld.com/virtualization/archives/2007/01/virtualized_mac.html
Well, Parallels has decided that unlike VMWare's moral conflict over the issue, they have no qualms over being the good guys (in Apple's eyes), for the time being. Marketing Manager Ben Rudolph responded to my pleas for an answer on the topic, and said that due to the EULA in OS X that forbids virtualization, Parallels will not be enabling users to virtualize OS X anytime soon. http://arstechnica.com/journals/apple.ars/2007/2/9/6983
Looks like both VMware and Parallels have the ability to run Mac OS X just they wont let the public do it till they are allowed.
