Well, you'd obviously have to store project files in a directory accessible from the network. You'd also need to edit the file locations in the System Settings-Workbench-Directories tab. But please note that the settings dialogs (system and/or active profile) can be very slow to open if you have a slow network or a lot of project files (such as data pool files).
You can export the project and ftp or use a program like PC Anywhere and transfer them to the machine you want to use. I do this all of the time. I create the projects and record on my desktop and upload to my controller.
Just as a side note you may not want to transfer all of the files to the other machine (items like the baseline reports).
But in the end doesn't it all come down to BEER? Beer is the ultimate answer to all questions in the universe so yes the answer to your question is BEER.
