Just joined the forum and noticed your thread as it's something that's increasingly an issue for me too, so thanks for the info you've put together. The thing I was going to add was, I've discussed the problem one-to-one with my main clients in the US and they've actually been really understanding about it. We've come up with a compromise where a small increment is added into the budget for anything I work on and it kind of spreads the cost between both the client and I.
I'm not saying for a second that everyone will be lucky enough to have clients as friendly as mine, but I reckon it has to be worth a direct conversation to see what can be done. Many of them didn't even realise it cost us even more money once the payment arrives in our accounts to change the currency and they were all pretty sympathetic about that.
