InDesign compatibility question

I'm going to be working with a designer on a joint project. He's out of town. I'm going to be using ID CS4 on a Windows machine, and he will be using ID CS3 on a Mac. We'll use OpenType fonts. We need to swap documents, work on them, and send them back to each other. In theory, this should work, right? Are there any problems with this setup? If so, please be specific. THANKS!
InDesign compatibility question
Forget the Mac/Windows things...especially with opentype, it's irrelevant.



The real problem is that the other designer is using CS3. While a save

back one version is possible via INX text will reflow and any new CS4

features will be lost.



In short, this is horrible way to work on a collaborative project. You

need to convince the other person to upgrade.

Bob -- thanks. OK, I understand that if he opens my CS4 document in CS3 (using the .INX interchange), then you report that there will be text flow problems and perhaps other problems. But what about the reverse? If I open his CS3 document in CS4, will that be a clean transfer? The truth is, he is going to do most of the work.

Should be okay but the moment you start editing text the entire story is

going to reflow so make sure he doesn't do any work on that.
