You may need to eleborate a little more but here are a few thoughts on that. If you were to purchase two copies of FPS Creator, install it on two different machines, I think you should be able to work on the project seperatly and merge what you can. For example, he works on one level and you work on another. Then when you are ready to combine, he saves all the media(Pictures, Models, Levels etc..), put it on your PC. Then you work through linking everything together and compile into one project. So Yes, I would think you should be able to do that.
I am counting on it for my team so that we may work on our stuff.
