This is a really interesting discussion. I have another suggestion. It's not necessarily better or worse than the suggestions above, just another possible style of play you could adopt. Also, I agree with Dave that the probe in the lower right (while it is a cool tactical idea) is weird in this opening. In this game white could just make the solid connection in the top right to limit black's potential at the top more and support an invasion later. There's no need to be fancy. You could go so far as to say that white's solid connection is the reason why black's attachment underneath isn't so great in this opening.
Some of the ideas below I learned from Go Seigen's book
A Way of Play for the 21st Century. This isn't the exact position discussed though.
If the game goes like other people have been suggesting though, black can play more tightly, with

the diagram below. This anticipates that white will make influence and preemptively erases it. This strategy is possible in this opening because black has played tightly on both sides (look at the marked stones).
For what it's worth, I think white should play 'a', even with the looser pincer (then black can switch to the lower right). I think 'b' is something of an overplay and just gives black what he wants. I know I'd be happy if white played 'b'.

In the diagram above there's no totally satisfactory way for white to make shape now. I think the best white can do is 'a', because 'b' will lead to an unfavourable fight and 'c' is even heavier than 'b' (after black just plays 'a' - white 7 isn't an important stone).

If white continues as above, the game looks a bit better for black because white played too many stones in the top right and black has already erased white's thickness, so can happily take gote profit with

. Note that 4 at 'a' looks like a good move, but it's not. White just plays the counter at 'b' and suddenly it's very hard for black to maintain connection along the top. That's because the 'a', 'b' exchange gives black shortage of liberties. Note that white now wishes that he could approach from the other side in the lower right. That exchange has turned into a bad move for white.
What if white fights though?

So white has to try something like this instead, but it's hard to play for a trade because white is heavy and black is flexible.

It's true that this variation would work even better if the marked black stone was at 'c', but that's only because white repeatedly asked to fight when it wasn't appropriate for the situation. That's why white should just play the soft knight's move in the first diagram, and before that, the solid connection in the top right.
If white plays the soft knight's move, black will get sente and won't have any weaknesses, but if the marked stone was at 'c', white could look forward to invading around 'd' later and the game would be easier for white.
