*grumble*

 From my standpoint, ICAP isn't implemented, and the barrier to
getting there is much higher than adding an option to rewrite_program.

I don't want to loop around to the whole 2 vs 3 question and thereby
feed the trolls, but it's not an option for me at this point. Even
when it is, I think there's a place for helpers like the rewriter;
sending the entire request through does not work in some deployments,
and debugging ICAP is a whole different kettle of fish.
