Short answer, "yes." We do this with all of our edit computers that go to the field. Long answer, "yes," you will have to copy all of the presets & easy set-up files into their proper locations. Search around, I promise, they're in there. Sorry, I can't be more specific without the computer right in front of me.
Thanks for the reply. I did find out yesterday (sent an Easy Setup to Tech Support) that the Easy Setups do contain the Custom Presets, which are not separate files (at least in FCP 5.0.4). I should have posted that information here. I apologize if answering a question I had already found the answer to was an inconvenience.
