I edited a full length feature some years ago where I had to edit at a client’s MacPro when his presence was needed, and edits on my time on my iMac at home.
All dailies and sound was captured on the MacPro’s internal drive. Right after i captured all the dailies and sound, I cloned the MacPro drive into another Firewire 800 drive and named it the same name as the drive in the MacPro. When I carried the drive home and connected it to my iMac, and opened the project, it was all online without needing to reconnect.
When I needed to work on the MacPro, I just took the project only, on a USB thumb drive, to the MacPro. When opened there it just worked fine. No reconnect. After working on the MacPro, if I took that project back to the iMac and it opened and connected automatically there too. Just to be safe, I set the drive as one of the targets in the ‘Search Folders’ setting in FCP System settings in both machines.
I did this back and forth for about 4 months editing alternately on both systems and keeping media at both locations too..
If new dailies were captured on the MacPro drive, I carried the Firewire drive there and cloned it again, so both drives were always identical. I used SuperDuper for the cloning, but you can also use Silverkeeper or Carbon Copy Cloner
When FCP opens a project, it simply looks for a drive by name and folder structure and doesn’t care if the drive is internal or Firewire. Clips, sub clips, sequences all connect perfectly. Also, FCP allows you to connect two drives of the same name, to one Mac simultaneously. Of course, I never opened the projects with both drives connected.
Not sure if this answers your query, but it’s another route.
