Premiere CS3+Cineform and working on both Mac and Windows
 

I have an editor that will be working on Mac with Premiere and I have Windows with Premiere and Cineform Aspect HD. The project is a HDV-project and I will capture to Cineform. I want to have the option of taking my editors project and work with in Windows or even giving back some projects. Is this possible? Do any of you suggestions on this or it works? What changes are needed on the Mac?
