This idea wouldn't satisfy the original premise of the thread that the 
file couldn't exist twice:
Has anyone thought of using the shell command "split"?   I have used 
split or csplit to vi edit small portions of very large ascii files, 
recombining the big file using "cat".   It would probably not have been 
any faster than using "sed" as the original author did, but you might be 
able to do more complex editing.
