I don't how much I can say since I work for VMware, but it's finding new uses all the time and I've personally brought it up with other teams. I'd known of it a while before seeing a presentation on how one service team used it. They had a stream processing problem where they were beginning to lag the input by up to an hour. With differential datalog the lag dropped to sub-second. It's seriously cool technology.
