Lexington crew seconded to Intrepid

Star Trek: Lexington (July 29) Sean Koury who plays Captain Freman "appears" briefly in the Scottish Star Trek: Intrepid fanfilm. He is a Commodore in the Intrepid episode and commands the Arizona C, which also gets a mention. How does he commute all the way from Ontario to Ohio and Scotland? Transporter? It's actually just his voice, a one liner, but it is an example of the growing cross-pollination of fan film projects.
