Here's a heretical notion: don't bother with shuffling your documents back and forth all the time. Work on the documents you need to be portable on your iPad, even at your desk. When you need to move the document, move it, and put it back on the iPad when done. Document sync isn't going to magically appear in OO3 next week, and OO4 isn't going to magically appear soon either. Wasn't portability the reason you got the iPad?
By all means,
file those feature requests but make it easier on yourself while you wait.
