In my case, the company I work for is a MS shop, but they were willing to entertain opensource CMS options as long as they were .NET because most of the developers have experience with that; I'm the only LAMP guy that touches our site.
I still got a lot a lot of the "we don't want opensource because it isn't as secure" stuff from IT. I just facepalm'd and tried to persuade them, but nobody's going to take the "SEO guy's" word over the IT director's.
Thanks for the info, ergophobe.
