for instance, I would give it "the_game_i_did_last_night_that_was_so_funny_even_if_i_loose.sgf" and it will tell me something like that :
black :
- nobi : 20 (xx % of the moves)
- kosumi : 40 (xx % of the moves)
- tobi : 30 (xx % of the moves)
- Niken-tobi : 5 (xx % of the moves)
- keima : 50 (xx % of the moves)
- Ogeima : ...
...
white:
- nobi : 37 (xx % of the moves)
- tobi : 12 (xx % of the moves)
- Niken-tobi :
- keima : 64 (xx % of the moves)
...
or even better with analysis of "things" like : tenuki, tsuke, peep, osae( maybe a bit difficult with one as I understand it more like beeing an intent not a move... or is it a move
I know that only statistics (or statistics only) isn't enougth to judge a game, but I will still like that kind of tools.
[edit]
Finally I did try to write one... first try here : viewtopic.php?p=165330#p165330

and a from keima
