I have. We rolled it out and tried to get our devs to use it. Every time we shipped a server with PVCS out to a remote office, they'd reformat it and use it to host MP3s. The one saving grace of PVCS Dimensions was it's enormous infrastructure, price tag, army of winged monkeys that you had to rent from PVCS to get it to do anything useful, and complete and utterly unusable user interface. This meant that app wasn't able to get a foothold in anywhere but the largest cube farms, where users had low expectations of their quality of life anyway. It was so obviously useless that nobody ever really used it after they spent their million bucks on the implementation. VSS was far more harmful- it was distributed essentially for "free", so thousands of shops adopted it, relied on it, and put their most precious assets into it. It's like giving machetes out to elementary school students. Microsoft should be ashamed for shipping that piece of dangerous crap for so many years, and not even using it themselves. Pathetic.
