Answer 1

If you're running Office 2003 or Office 2007, use OffiSync. It's free.

Answer 2

Syncplicity works for me, although the sync sometimes takes a little while...

Sync files with all your computers. Access them from all your mobile devices. Share them without changing your work habits. Make sure everything is backed up. All with the control and security you need.
