Always enjoyed the intimation that Cochrane was the fictional version of Roddenberry in First Contact, specifically this exchange:
COCHRANE: Please ...don't tell me it's all thanks to me. I've heard enough about the great Zefram Cochrane. I don't know who writes your history books or where you get your information from, but you people got some pretty funny ideas about me. You all look at me as if I'm some kind of saint or visionary or something.
RIKER: I don't think you're a saint, Doc, but you did have a vision. ...And now we're sitting in it.
I also wondered back when Majel was on Babylon 5 her character made a statement where she said something to the effect as she was now on board the station that this was her husbands dream. The way she said it with such emotion and conviction made me wonder if B5 had captured Genes vision and not DS9.
