Is it possible to do a one way sync of iPhone voice memo's to a PC?

There is a few hacks online allowing you to sync your iPhone with multiple iTunes instances, however I must admit that I adapted to the single sync solution. I sync everything with iTunes on my Mac, which means I always have the information with me, either on my phone or my Mac.

You could use the action button (the box with an arrow pointing out) and email it to yourself, or you could use itunes.
