Although not the Holy Grail, I think an "off-line" utility would be a 
sufficiently useful tool for the majority of my applications. I still use 
Ian's viewer and find it useful for checking without going through a 
Gerber/Print cycle.
I can think of three distinct situations where I would use it 
(generally on SMT through wave boards)

1) After placement of top side, through hole parts. Arrange SMT 
stuff on the other side.
2) Arranging Ref Des and other text to look right from both sides.
3) Producing a placement file / drawing for the SMT parts. As far as 
the SMT guy is concerned, that is the top side of the board.

Number 2 & 3 would only need to be done once and an external 
tool would be fine. It could be desirable to flip back and forth with 
number 1 since placement is an itterative thing, but beggars can't 
be choosers.

Maybe this will all become academic when the new version comes 
out. :-)

Steve.
