<p>What I do is use Dropbox along with what's called "junctions" or "symlinks" in the computer lingo.</p>
<p>I moved the main data folder to a folder in Dropbox and then I use the mklink command (vista & 7) or Junction Link Magic on XP to make that folder viewable as the OpenLP datafolder. Then on the other computers, I install Dropbox, set it up the same way, and do the same process. This of course can cause a problem if two people are in the system at the same time, but it works for us, becuase that rarely happens. There's supposed to be the ability to work with MySQL soon, but last Time I tried that it didn't work. </p>
