...and don't forget about Barclay in IFM, which takes place in 2383, over 2 years after the current point that Voyager is at in 2381. He came to Challenger from the FC fleet through the transporter relay network, but he doesn't serve on Voyager. He's on the Galen. I think everything will work out with the Voyager crew, and in turn, the FC fleet in terms of still being able to access the AQ from the DQ. They aren't going back to the status quo for the series in these books.
