I worked at an AV company where I wrote a small video capture application that feature some basic CMS features. After a while it started to become a pain to maintain, so we decided to look for something off the shelf. The first vendor to come in and demo a product showed us a UI that was our design, pixel for pixel, with only the name changed.
Are you sure that wasn't intentional? In enterprise sales, it's fairly common to customize the demo to the client. I've been in situations where we deliberately made our software match the prospect's branding as closely as possible.
