As you might imagine, there are many overseas or non US AdSense publishers. I personally am located in New York, so I do not understand the complications with accepting US payment outside of the US. But I do sometimes receive Canadian money and sometimes I need to do wire transfers to pay companies outside of the US, and that is somewhat of an inconvenience. There is a thread at DigitalPoint forums named New Payment System on the Way which tells of an automated email being sent back to those publishers that ask the question about receiving direct deposit or other forums of payment. Google tends to suggest, in those emails, that they hope to offer new payment options in the months ahead. However, there are those that say Google, when asked in person, say it will never come.
