I don't read it like that. From my point of view it's like saying if you sell virtualization as a way to isolate different OSes + applications for security reasons (compared to cost savings and all associated from using this kind of technology), clearly you better think twice about that. And really, it's pretty much always a selling point when you talk to a marketing rep or your PHB or her/his PHBs.
