I haven't seen all of DS9 (local station buried it in first run in the middle of the night), so I'm not up on all of the continuity points of the series. But Showrunner Terry Matalas is a huge Star Trek fan (like me a big ST:TMP fan at that, but has talked a good bit about TOS, TNG and DS9 as well) and he got his career start working on Voyager and Enterprise.
