You know, the one thing that really bothered me about that scene was that there only seemed to be 12-15 people there-- at the Captain's funeral? Otherwise, I enjoy the episode (although the thought of aliens waiting to trick you when you die... a little creepy).
I just take that scene as it was a more intimate, private affair for Officers and others that had actually worked with Janeway on a daily basis and that another memorial service had been done for the entire crew at another time.
Then again, if you ascribe to the notion that those scenes were all in Janeway's imagination, it would make sense she would see only the people she'd worked with one-to-one.
What a bitch
